Non Linear Dynamic Contact with SolidWorks Simulation

[@thiago-tcsengenharia1327]

Thank you Nick !! You make an difficult subject (Non linear analysis) turn to easy - congratulation - From Eng. Thiago Brazil

[@AnNguyen-kz4pk]

That's all i need in my thesis. Thanks so much :3

[@alexertel9368]

I hope you know, I spent the last week trying to get around using an initial velocity because I didn't realize you could apply it to a body. I applied it to all of my surfaces and edges but then had a weird result where the skin/mesh of my object had a massive stress in it. I wish I found your video earlier.

[@techscifun7846]

Perfect help for my thesis. Thank you so much.

[@deepakjohsh7748]

Thanks for Quality content like this. Appreciate it.

Hey Nick, your video is so helpful, really your presentation of nonlinear simulation made very easy to me.

[@derekfricke3363]

Well presented.

[@pramitmajumder6355]

Good content!

[@pramitmajumder6355]

Wonderful!!

[@محمدالخصيبي-ش9ج]

well presented

[@blalahamza4258]

Your video is so helpful, thank you so much

[@ahmetusta6821]

Bravo👍

[@HamadBuhamad]

Thank you for your video

[@kaysseibrahim6477]

thanks a lot for these information..... i have a couple of question if don't mind ...... how can i simulate a blade cutting through a plant stem (for example ) ..... if you have somthing help me i well be greatfull .... any way...thamks alot

[@pepedecoatza]

I would like to know why you did not mention or make assumptions about the roughness of the surfaces bodies. Thanks for the video

[@MAMotinSobujsobuj23]

Thanks

Hello, If you fix the projectile in 5:11, are you not also making it rigid?

[@JuliDavidov]

so cool :)

[@toshibamaster2210]

Is it possible to simulate the delamination of the coating from the substrate?

[@rodolfopereira2142]

Can you simulate a ball joint made in polymer: example ABS?

[@andyblue001]

Hi do you know any value or reference for damping when using nonlinear dynamics specific for bullet impacts lets say, playing with the damping values for alpha and beta has a great impact on the results, i mean is there a way to at least correctly input damping specific for bullet impact simulations in nonlinear dynamics, thanks..

[@johanjairporrashuaman7768]

¿Es el mismo procedimiento para un Análisis Dinámico No Lineal de un accidente automovilístico?. En en caso de que una motocicleta impacte a un automovil que esta estático.

[@domingovega2270]

Casi lo mismo, solo que las restricciones aumentan y sería adecuado crear solidos no fusionados para tener nodos refrencia para el impacto

[@1MoAndDashIt]

Hello, with your method, can you animate impact between the two bodies or is it set?

Hey Nick, thanks alot for this information. It's incredibly helpful and I'm glad that there's information like this available for students and the like in the early stages of CAD simulation. I have a question concerning a simulation I'm trying to run. I've approached different sources in my area but have yet been unable to discover how to succesfully run the simulation. I'm trying to axially expand a cylinder by running a rigid conical mandrel through it. I assume a 2D axy-symmetric non-linear static simulation should do considering the material (a typical steel) will behave non-linearly and the mandrel can be forced through the cylinder by a constant force. Essentially I would like to deduce the required force and if possible the principal or Von Mises stresses within the cylinder during expansion. Do you have any suggestions? My thanks in advance!

[@gosimulation6850]

Hi David, If I'm understanding this correctly, there are a few ways to handle a problem like this. One way is through thermal expansion. If you go the thermal expansion route, then the two parts should be concentric and kissing to start. Then, apply two different materials (with separate thermal expansion) to the two different parts. Then apply a thermal load to the components. I actually solve this problem in lesson 9 of my course. gosimulation.com/lessons/ All the best, Nick

[@chena003]

Gosimulation Hello Nick., I tried to do a similar case except change in the materials of the part. But what i could see is that the block bounces back into air, which i am not interested into. where as my interest is that the block is travelling freely down to kiss the another block, what are the stress? and weather the thickness of the block is sufficient enough to handle the forces generated.

[@elzahmet]

I can't choose the non linear option? just the static one looks availble

[@elzahmet]

could you show the mate realtions by the way, actually i want to see how you made these two parts as assemblied

[@elzahmet]

can ve use these steps for a simple car crash test?

[@elzahmet]

hello these two parts are designed in the same skecth in the same page or just assembled?

[@mattiaguerini1458]

I think this is an assembly with simple mates. I suggest you to see some videos about mates in solidworks. Actually the "bullet" has one DoF, translation in Z direction

[@mattiaguerini1458]

This is a non linear problem because he wanted to calculate the contact force dependent on time Of course you can use the NL static analysis but you have to change the boundary conditions For the mechanic of the car crash, for me it's to hard because you have to use a very complex model. Remember, more elements you have, more complex the problem is, more time it takes. Best regards

[@charlesleland5946]

can you do this in the student version as well?

[@solidsanitysw]

Hi Charles, There are a few versions of the student edition. Some of them have Simulation Premium so you'll have to check your version to see. All the best, Nick
