Dear KZbin, please base my recommendations on this video. This is exactly what I want to see more of.

[@mRcOOL5YO]

Dear Dan Ko, your request have been registered and saved in the recor......wops, dropped it. We will instead recommend you "This week with John Oliver" and "Mr Tfue" videos with a direct wormhole to both "Keeping up with the Kardashians" and "Instant regret" playlist, Kind regards - Yotbe, probably.

[@witgangyounotube287]

yeah and you will see this video recommended over and over instead of newer video's from same channel:/ i've watched this channel for a long time yet this video only now popped up in the side list after watching some other 3d print related stuff..also on my youtube recommandation page are only video's i've watched or a good 90% of them..epic fail..

[@lukeandliz]

​@@mRcOOL5YO the benefit is 3 years later, you forget you saw the video and get to watch it again🤣

[@mirzacenanovic]

Love to see proper engineering applied to design! As you have pointed out, the MAIN introduction of error in the approximation is the assumption about the boundary conditions and of course material properties, PLA under load behaves highly non-linear and, as pointed out, the FDM technology causes the resulting material to behave anisotropically. This means that these tools cannot and should not be used for analyzing absolute stress distribution or decision making due to absolute stresses. That said, comparative studies can be carried out. Your discussions about proper boundary conditions are superb! Keep up the good work! The makers world needs more high quality videos like this.

[@FBPrepping]

Border conditions can be assessed by destructive testing, while taking in account and adding to the database the conditions the 3d printed part was made. Although that testing is not made under any industry standard, it is valuable data though, because it considers the worst case, real life scenario.

[@3DPrintingNerd]

Very informative! Thank you very much for this, Stefan!

[@nobocks]

better than your shit channel especially you are full time on it !

[@DogsBAwesome]

Nobock really!!! I bet you are fun at parties, oh wait you don't get invited.

[@nobocks]

Don't attack this guy in person, just his content, thank you !

[@MiklaDfar]

As a previous engineer pretty familiar with FEM (ANSYS) you did an EXCELLENT job with this video. Not sure about Fusion but you could have simulated the wall with a fixed constraint to not allow movement in the -X direction on the back of the support surface. Also, you might want to include design constraints such as being able to easily mount the bracket. For instance, your design makes it very difficult to securely attach that center and bottom hole with a Phillip's screw as the bracket would impede the screwdriver. Love that fact you correlated the analysis results with actual testing.

[@adamluter]

CNC Kitchen continues to grow and blossom! Excellent video, you are a real hero of the community!

[@steelmilkjug]

Great video! You said the KEY POINT in Engineering/Design/Analytics: "If your assumptions are off, your results will be garbage".

[@joscythe556]

There's so much more to FEM than people think. I dare to say it's one of the most underestimated parts of engineering, because people assume that "pretty colorful images" guarantee accurate and realistic results. Even if you choose the right load case and boundary conditions you might still use the wrong element type or solver and get numerical artifacts without even knowing ( if you don't know what to look for).

[@android4cg]

One of the best professional 3d printing channel on KZbin. Great!

[@alexandrevaliquette1941]

THIS IS THE VIDEO THAT I WAS HOPING FOR!!! I had to learn about stress analysis in Fusion 360 for my 3d printing designs. It will confirm my intuition before starting a print! I will be able to compare design A vs B vs C vs D and only print the two bests ones!!!! Thank you so much Stephan Alex from Québec, Canada

[@EvanRisk]

When you added the friction less surface to the back of the bracket I immediately shook my head. Then you added a note all was good.

[@haythamhakla]

Im not too familiar with stress analysis, but could you explain what is the issue with the frictionless surface assumption?

[@rikdol]

@@TheGoodoftheLand The problem with commenters like yourself, is that you don't take time to listen to information in the actual video, and rather bash a comment you don't agree with. Or, in this case, defend a stupid question. Because the reason why "using a friction less surface is bad" , is given directly after he applied it in the video @9:53. Just because you don't know about a topic, doesn't mean no one does.

[@haythamhakla]

@@rikdol This is an informative video for the general public. People like myself watch an learn from it. The question I asked may sound stupid from the point of view of someone who is more familiar with the topic, but for me, it is totally reasonable. I watched the entire video and the reference @9:53 still didn't clear my confusion about this point so I was proactive and asked for clarification. If you know better, please go ahead and explain this point.

[@rikdol]

@haytham hakla a frictionless surface will be unable to move away from the wall. Earlier in the video ( @1:50, look closely to the bottom part) it shows that the part is bending. When a surface is set to be frictionless, it will be unable to move during a stresstest. So a test like this for stress and bending or warping of material under high load, won't be realistic. Another example of the part moving away from the wall is @20:00, circled in red..

[@haythamhakla]

@@rikdol Thanks for clarifying

[@JohnOCFII]

Stefan - that was fantastic! I learned quite a bit watching this video. Thanks for taking the time to share!

[@MarionMakarewicz]

I'm glad you did this video. It's very helpful to learn how to make your parts stronger. When Joel first did his brackets, it was pretty clear that they weren't the best design. Simply looking at rafters for roof construction demonstrates an optimal design of a truss. Regardless, I did appreciate the basic idea of making shelf brackets for my filament rolls. They work great.

[@CreeperInDisguise]

Ah, I love these kinds of videos, I always learn something new! Keep up the great work Stefan!

[@CalebDiT]

Oooh, you got some o' that stronger, yellow filament! Nice! If it's possible in Fusion 360, make sure your fillets are curvature continuous, otherwise there might be imperceptible discontinuities that can be treated like cracks. Another important thing to consider is controlling the failures. If a failure at spot X would be dangerous, but a failure at spot Y would be safe, make sure there's a higher probability of failure at Y.

[@yeroca]

This is exactly the kind of video I was looking for, thanks! I am new to mechanical design, but had heard of FEA in the past, and wondered how difficult it would be to use for designing my functional parts.

[@joetke]

OMG! Noch einmal! The German engineering excellence is not a myth! Rigorous demo. Love it. Thanks a lot Stefan! I used to work in Lahr, Germany, 50 km away from Strasbourg where I live. I did appreciate the seriousness of German engineers (IT sectors) but never understood their humor - still wondering whether it exists ;) - my German language knowledge being so wanting...

[@engineeredaf1920]

What a great video!! I'm so glad you included the lesson about the FEA constraints at the end! This has the greatest influence on the analysis results. I think normally, fixed supports for bolt holes is not a good assumption because they should allow free rotation with linear support at bolt head(Fixed support makes part artificially stiffer) But looks like your failure correlated well!

[@LukePettit3dArtist]

Many of us pointed Joel to your video on this subject when he was making those brackets :-) On his second video on it he mentioned you and that video. I'm so happy you are doing a follow up to it. Thank you.

[@deanallenjones]

Joel the 3d Printing Nerd was right to send me here. You have much to teach me

[@chibani_gl]

Thanks for this really informative video. The simulation tool is my next go-to. Thanks again.

[@trashblob]

Thats really cool! I did not know about this Feature. I have to play with this a little bit later!

[@hectorsamuelgarcia4384]

Good video, I love your videos using stress analysis and optimization from Fusion 360.

[@DigChaos]

Excellent video Stefan. Loving Fusion360, can't believe its free!

[@valgov3001]

Nice to see an engineer's perspective. I had no idea the simulation in fusion 360 was on this level. I'll definitely be using this going forward!

[@sergarlantyrell7847]

Just watched one on topology optimisation and all the way through was thinking 'Sort your boundary conditions out!"... Nice to see him come back to that at the end of this video.

[@ELEKTROGOWK]

That is a great result!! That is way enough for a bookshelf or what so ever.

[@fataxe1]

I'd love to see Joel do a video himself where he makes simulations himself. It's always useful to have another set of eyes from a different background for design problems like this. 3d printing has been an interesting area where you don't need engineering to make things work, but learning tools from the engineering tool box can help you so much.

[@datta3ya]

amazing man that was very clear and I have got a good picture on how to validate with real testing Thanks

[@flubba86]

I love playing with the stress analysis features in Fusion 360, and this was a very interesting video. But I am disappointed that the end result was "make it thicker", I was hoping you'd do some kind of automatic structural optimisation. You don't need finite state analysis to tell you that a thicker part can take higher load then the original.

[@EPortillo5000]

Well the analysis tell you where to make it thicker and where is not needed.

[@JackZimmermann]

Great stuff! Must learn simulation in Fusion360.

[@mspacone]

Nice video mate! Thank you!

[@hillfortherstudios2757]

I think it would be interesting to see a generative design and how it would compare during this analysis. Thanks a lot for the video Stefan! Good Job!

[@MrTigerpirro]

+CNC Kitchen I would like to see you try adding a thin section in the middle (like an I beam) with strengthened "cutouts" for the screws instead of thickening the material. If you print from the base and up this should avoid having to add support material.

[@aDarkSeoul]

Excellent topic!

[@Sir_Baraon]

Really motivative to try the features in F360 on my own now, thanks! ;-)

[@ronmac1832]

Very useful video! I'm always curious about exceeding material strength in compression for malleable materials. Our PhD analyst is always asking me to beef up areas exceeding yield in compression, but it has been awhile since I've seen material compressed to failure. Thank you!

[@dejanjonic2592]

I love your videos, we all learn something new from them. Correct me if i am wrong but your test scenario here is more suited for hanger and not shelf bracket. Shelf bracket should have load concentrated on the middle of horizontal part (if you simplify it with one force) or distributed evenly over entire length of horizontal part of the bracket. You would get other results then. In any case awesome video and a lot learned about fusion 360

[@user-qx7tm5df8j]

[@frijoli9579]

Cool video. This is the difference between brute force engineering vs mathematical. They both work. One is typically quicker to market, and the other just works.

Hehe ja Autokorrektur hat zugeschlagen 😅

[@petersnape1537]

Stefan, Very nice video. You certainly improved on the original design and taught us all a few things about the finite analysis package. However I would like to point out that the original testing concept was flawed in order to simplify the testing. The final loading of the brackets was to occur with weights more or less equally placed on the front and rear rails. Consequently this would place greater shear forces on the top inner corner of the bracket. I suggest that under these conditions the only point to fail in the bracket will be that same top left corner. and I also presume that the ultimate load would be less than half of the loads that you measured (probably a lot less). This mode of loading could be readily tested by placing a light weight cylinder on top of two wooden blocks in the place of the rails and then loading the cylinder using the same strap tensioner. The finite element simulation should also be changed to involve the two weights (and don't forget the small twisting force due to the filament spools forcing the wooden rails apart).

[@ACota-dk9qw]

Awesome video.

[@fugixi]

Nice video! I love these. Did you ever test the revised version at the end of this video?

[@victorforslund4047]

Great video but I have a suggestion. This is basically "euler bernoulli beam theory" By increasing the area of inertia the structural strength increases. You can test this by flexing a ruler. The side with the greater inertia is harder to flex. My suggest is that the middle support in the triangle should be flipped 90 degrees to increase its inertia. But anyways this was a great solution and a great video

[@nono9370]

Victor Forslund hard to print if you want it to remain in the middle

[@paulmarinis6069]

Hello Stefan! Nicely explained! Maybe you could add a fixed contraint in a small area just at the back of the 3 bolts also without the frictionless support.

[@avejst]

Wow, two KZbin's united work together👍 Nice work, thanks for sharing👍😀

[@cigp]

very handy , thanks!

[@KieranShort]

This is really awesome. What would be the effect of adding, say 2mm thick orthogonal strips which protrude from the cross member girders. This would make them more of a cross shape in cross section, and I think (in my special custom buckling simulation, in my brain) that configuration would spread the load stress more evenly and perhaps improve buckling load resistance. Great video thanks!

[@1q1q1q1q1q1q1qw]

very cool video i would suggest a test where you put a woodboard on top of two breakets anthen pull down inthe centerpoint of the board

[@fabiomenegattidemelo3846]

Congratulations for your work! Have you considered increase the area moment of inertia of the lower member instead of just increase its thickness. I mean, you could try designing a "T" cross section, for example. That would reduce the normal stress at the lower member while keeping a lower mass. Again, nice work!

[@Deqster]

Adding a very minor relief cut on the back surface of the bracket near the bottom screw would allow you to create a small constraint surface just at the bottom corner. This would prevent unrealistic results due to constraining the entire surface.

[@CNCKitchen]

True!

[@Deqster]

@@CNCKitchen love your channel by the way, especially your methodical but garage-doable testing regiments! Also your video on heat resistance testing of various materials led me to be able to powder coat PLA! More on that another time

[@RJMaker]

Fantastic! I would love to see the stress numbers of a standard (.04) printed part.

Very good video Stefan. Can you do show us how to do a similar analysis using FreeCAD?. Keep up the good work!

[@redpug5042]

iirc, fusion will also do generative design, where you tell it what geometry you want, and where forces will be, and it will generate an optimized structure to support it.

[@IronMan-yg4qw]

nice. more on this subject please!

[@j...bro.]

Watch those bolt spacings to load points fasteners as close to load points for optimising load capture without inducing torques.

[@BaristaPablo]

im nerding out so hard right now

[@stevesloan6775]

Great work! All the simulated shapes reminds me of engine conrods.🤓 Is there a follow up video??

[@56Seeker]

Three quick observations: How did you get a scew driver to the middle fixing hole? (Every bracket designer forgets this) Would changing the bottom member to a triangular cross section affect the result? The bottom member has a high slenderness with respect to the plane of stress; and narrower, deeper section may have performed better. Great video, I really appreciate your work.

[@LuxBacelo]

2:23 "We are working with mostly that are hollow and Fusion360 is just not made for that." YET. I think they will add a most precise simulation for FDM print in the future. Great video!

[@thoperSought]

that's amazing

[@MT-em8mg]

I am just wondering about the material and process data due to the 3D printing process. It seems that the FEM simulations are performed with full material, but printer settings such as filling, wall thickness ,or layer height are not considered. In this case, why do the simulation results roughly match the test results? Thank you very much for your help!

[@gustavomanuelreanopulache5314]

Free question, it is possible to simulate the gcode generated by 3d printing to check if the grid type is the most acceptable. Thank you greetings from Peru

[@TheRealStructurer]

I hope that since this was posted the functionality is still around in the free version. I’ll will try this on a hook I’m making 👍🏻

[@yuthokr01]

Great intro to FEA methods, going to show my high school robotics students. But I had a question - you use von Mises stress criterion, which I always thought applied to metals, but not for polymers (and certainly not anisotropic composites and non-annealed 3d printed thermoplastics with its inherent planar shear path). Does Fusion or any other basic solid modeling/FEA package feature stress criterion more appropriate for plastics?

[@vincentbrandon7236]

Really cool. I think I may like 360 over Creo. I think a visit to home depot would have been useful. Concave ridges are super nice and let you take material from one side and put it on the side under compression (all the trusses are rounded). WaaaY more time to draft, though. Filets tend to break.

[@lezorn]

19:00 Bless you

[@fraserdaniel3999]

In my limited knowledge, I have learnt that different printing parameters change the properties of the final part. Does the simulation take all of that into account?

[@IsraelMolina1997]

The analysis is for 100% infill? How i can configure the analysis for 15% infill? Thanks for the awesome video!

[@Nevir202]

Given your failure mode, what if you changed the upper arm, such that you used a significantly longer screw, which went into that upper arm, with the head of the screw ending up 25mm or more away from the wall? Having a steel rod present there would help with any buckling and having the support directly in line with the tension force would make pulling it away from the wall much harder.

[@1dayhabit]

Thanks for creating a very informative instructional video. Personally, I think that true optimisation would mean creating a design of equivalent mass to the original design but stronger, or the same strength with less mass but perhaps I'm just being very picky.

[@hammerfallen12345]

Hi! Is there a program for checking strenght on a 3 model? Where we are now with 3d printer program and Cad program i think we should had develope a program for this. Maybe there is already one that come with more expensive cad program. But there should be one free that are for plastic material by now

[@johnesteer9537]

excellent ....i used to do some fea about 20 years ago...did not know fea available on f360..is cloud buckkling available free for 'hobby' can you constrain to simulate washers?

[@MrHuggaga]

so now to do anisotropic simulation then? does fusion support it at all or will i have to use a dedicated FEA-program for this? I mean, the ones included in Fuison, Inventor or CATIA are way simpler to use than ansys for example, so it would be nice if i can do it in the CAD program...

[@kennethnilsson6976]

Great video. Kind of hard to use the middle screw hole in the last design. Not much room to fit either the screw or screwdriver without hitting the stabilising part.
