For a proper sheer test you really need to use a torque wrench if you are going to bolt plates together. The tensile force creates friction between the plates which counteracts the sheer force. Without them being equally torqued you cant be assured they are facing the same sheer force.

[@crumbscheek]

Exactly my thought. Greetings from an automotive engineer

[@brianwright9514]

And using 8.8 steel bolts. Should have used 10.9, something more widely used.

[@75L48]

Cringed heavily while wathcing that part. Even more those washers and nut on the titanium bolt. For this test you idealy want to set correct preload to the fastener. 8.8 is most widely used fastener in Europe friend. Chinesium tools most often used inferior 5.8. 10.9/12.9 are high strenght fasteners not used for basic construction work, you will not buy these readily in hardware stores.

[@mmholling87]

Aerospace guy here. I honestly think the friction between the two plates is negligible when under a shear load. If you're relying on the friction between the two plates to aid the strength of the fastner than you're already in big trouble. The gap in the two pieces of metal only exists after the bolt has already has already begun to yield. Not in every scenario but typically the fastner is weaker than materials plus when you torque a fastner the torque value changes between shear or tension. The same bolt and nut will be torqued to a higher value in tension than in shear. I would like to see the numbers with the free running nuts hand tight and then torqued. I could be completely wrong...

[@75L48]

@@mmholling87 depends.. there are commonly used friction joints with single bolt transmitting tens of kW without any slipage. Bolt only provides necessary joint pressure, there are no keys. So that tells me there is significant friction for this to work. Also the jointing planes are not machined, just simple somewhat flat parts-still works.

Having worked in a mechanical test lab I can assure you, there are steel alloys out there much stronger than titanium.

[@thibautdeveraux]

Steel range from something like 300 to 2500 MPa of ultimate tensile strength depending on the exact alloy and treatment. Titanium resistance can also vary a lot depending on the alloy. So it depends... And the tensile strength is far from being the only criterion.

[@rafaelthome6251]

I agree. We must consider also both bolts' diameters. Titaniums' is larger than steel's; shape has also influence in performance, all this without considering manufacturing process. Regards!

[@brianwright9514]

Yeah, the steel bolts used in this test were a pretty weak grade. 8.8 bolts are only 800 MPa UTS. 11.9 bolts, which are pretty common are much stronger than titanium bolts.

[@anomamos9095]

The shear test was not optimal for the titanium as the washers needed to space it out didn’t provide enough support to keep the plates from deflecting. There’s a shatter test for titanium fasteners, from what I have heard steel has a better shatter resistance.

[@Dave-G]

First of all, you cannot compare bolts with different diameter, seems like we have a dia. 4,8mm steel bolt and a 6,35mm titanium bolt. And of course you must use a torque wrench for tighten bolts at same Nm value

[@spacepope-1]

Well good thing this ismt a strictly scientific test and is mostly for entertainment

[@jeanladoire4141]

I'm a blacksmith and had my tries at armor making. In buhurt (medieval armored combats), steel and titanium armors are used in competition. The thing is, titanium is less protective than steel. Titanium, with the right alloys and tempering can have the strength of steel, for less weight. BUT it does not have its ductility. Titanium will flex, but will not bend, it will snap instead. Steel will flex too, but if overloaded it will deform, thus absorbing the energy like the chassis of a car. The strongest alloys of iron will be stronger than the strongest alloys of titanium however, but it's insignificant for most applications. Titanium is good for saving weight. But it is expensive as shit, and very hard to forge (weird heat treatment, springy while heated etc), steel is cheaper, strong too, but heavier. But it will bend when overloaded, wich can be life saving in some situations.

[@custodeon]

the fact that the cumulative shear strength of both bolts' threads was higher than the tensile strength of the main bodies fascinates and bemuses me

[@Totalinternalreflection]

Yeah that’s kinda how bolts work

[@johneddys2351]

Strength of materials be like it do.

[@mixter7x7]

titanium alloy grades are infinitely variable. making something from titanium does not make it stronger than steel. the most necessary component of the titanium is it's light weight to strength in flight applications as well as being non magnetic for flight instrument interference. your shear test was not equal / or sterile. the threads of the steel bolt were being sheared while the unthreaded shank of the titanium bolt was under shear stress. bolts intended for shear load have the applied load shearing on the shank - not on the threads.

[@napoleontheclown]

Melting point is another factor that favors titanium. You can get titanium a lot hotter than steel before it loses substantial strength. In aerospace and spacecraft heat tolerance is crucial. Another big advantage, in terms of marine applications, is when titanium oxidizes its "rust" is a strong layer that effectively seals the metal beneath. Iron, on the other hand, makes rust that is very brittle and porous, allowing the rust to keep eating deeper and deeper.

[@johnbarron4265]

This is a cool test, although in the shear tests there are some unwanted effects. As the press pushes down on the upper plate, the offset force causes the plate to pivot outward, creating a gap that gets bigger and bigger as more force is applied. So the plate effectively turns into a pry-bar, pulling the bolt head in tension and bending it in addition to applying the shear force. I think the test would be more representative of true shear if the shear load was applied by pulling on the plates, similar to the setup used for the tensile test. Also titanium is about half as stiff as steel, so it stretched about double the amount before yielding, so the upper shear plate pivoted about twice as far, meaning the titanium bolt received more tension and bending load than the steel bolt during the shear test. Despite this, titanium still came out on top in the comparison!

[@sambrown7950]

Because of the different dimensions and thread cut depth, shear test wast very scientifically precise.

[@bertnorticus1662]

Nice. Also, in the sheer test, when load was on, the bolts slipped over eachother causing a sharp yank which would've stressed the bolt suddenly affecting the results.

The grade 8 that is being used is also a vented bolt.

[@joeprimal2044]

@@blankblank2345 I think the empty pipe will fail much faster because once it starts to bend a crease can form and it will fold. It seems to me that the concrete filled pipe would be very resistant to folding because it would have to compress the concrete to do so, and concrete doesn’t compress. I suppose to get the full benefit of that you would have to cap the ends to keep the concrete in the pipe. In any case, I’d like to see it put to the test.

It’s a misunderstanding that titanium is extra strong. It’s the strength to weight ratio that is superior to steel. Not the overall strength. A lot of this has to do with what alloys you’re talking about too but generally steel is stronger than titanium. Class 8.8/grade 5 is a medium strength steel bolt and that’s why titanium outperformed it. Had it been a grade 8 bolt it would have easily outperformed titanium.

[@kireduhai9428]

This. Volumetrically, steel outperforms titanium every time - and alloyed steels usually beat alloyed titanium, too, especially with the right grain structure. But weight-wise, titanium usually wins, and easily. You can get a lot more strength per unit weight from Ti.

[@mihaiilie8808]

To get the true results in your shear test, it's important to have the proper size hole to fit the bolt. Also, you sheared the 8.8 bolt on its weakest part, its thread. The full shank of the bolt should go through both halves of the material, and it should be brought to proper rated torque for the test.

Titanium is only really necessary for weight reduction or some other small reason. It's better to say that titanium has a better strength to weight ratio than aluminum than to compare it's strength to steel. Steel overall is stronger and stiffer. Stay with steel. You may have noticed that the titanium bends more before failing which is not what you want. It means it's softer. Titanium is also crazy expensive by like a factor of 3 or 4 since it is a novel material that's difficult to mine even though it's plentiful in the world. Not worth the cost.
