100 steel bolts 🔩 would weigh around 1 kilogram. Imagine on a space ship 🚀 there may be a need for 20,000+ of these bolts. That's 200+ kilos of steel. Titanium literally offers nearly the same strength but cuts the weight in half. This is significant.

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.

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.

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...

@@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.

You used a weak grade of steel alloy. Why not use 12.9 grade alloy steel? Why only 8.8? Perhaps do another test comparing 12.9, 8.8, and titanium. Be interesting to see how much stronger is 12.9 by comparison.
@mixter7x72 жыл бұрын
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.

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.

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!

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.

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.

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.

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.

Nice test. Final results are little bit misleading and show smaller difference then it is in reality. The moment bolt starts to stretch or deform in anyway is considered a mechanical failure because it stopped doing its purpose. You can clearly see at 3:20 bolt is already starting to stretch at about 3000 on the display, so if just kept this force constant bolt would have snapped eventually as well. The fact it lasted all the way to 5000 is completely irrelevant. Titanium on the other hand barely malforms at all until it fails. This makes titanium probably twice as good over steel. Not just 20% better the shown results would suggest.

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.

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...

@@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.
Glad to see this as a reference of my determination for buying iPhone 15😵
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.

You used a weak grade of steel alloy. Why not use 12.9 grade alloy steel? Why only 8.8? Perhaps do another test comparing 12.9, 8.8, and titanium. Be interesting to see how much stronger is 12.9 by comparison.
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.

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.

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

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.
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.

No. But in some households is a hydraulic press.
The grade 8 that is being used is also a vented bolt. It is used in vacuum systems to prevent creating a virtual leak and to allow the bolt to be removed without it having a trapped vacuum underneath. The shear test in this case is very inaccurate due to this and the other reasons people have pointed out already.
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.

Something a lot of people also don't think about with space craft is that you need not just strength but many other aspects as well such as weight, corrosion, properties in a vacuum and other things
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.

I know this is just a basic test for KZread, but a proper comparison would have two bolts of the same design. These bolts have different heads and thread lengths. Also the specific alloy of each bolt should listed, along with any heat treatment that may have been applied. These parameters can have huge differences in the strengths of each metal. A general comparison of cost would be nice too.
It depends on which steel and which titanium. Titanium is around as soft as iron. But titanium alloys can be way harder and way stronger. Some titanium is about as hard as a coat hanger. But in general Steel gets harder and tougher, titanium is generally more ductile and shock resistant.

Nice test. Final results are little bit misleading and show smaller difference then it is in reality. The moment bolt starts to stretch or deform in anyway is considered a mechanical failure because it stopped doing its purpose. You can clearly see at 3:20 bolt is already starting to stretch at about 3000 on the display, so if just kept this force constant bolt would have snapped eventually as well. The fact it lasted all the way to 5000 is completely irrelevant. Titanium on the other hand barely malforms at all until it fails. This makes titanium probably twice as good over steel. Not just 20% better the shown results would suggest.
