i have a question. I understand everything about Young's Modulus but, when they say a material has for example 210000 N/mm^2 , what do they mean? that it can handle 210000N/mm^2 in the elastic region? and then it goes to the plastic?
@TheEfficientEngineer4 жыл бұрын
Young's modulus, yield strength (the stress at which a material goes plastic) and ultimate strength (the stress at which a material fractures) all have the same units. So it doesn't make sense to say "a material has 210000 N/mm^2", without specifying which parameter we are talking about. 210 GPa is a typical Young's modulus value for steel, so it is likely that in this case the 210000 N/mm^2 is Young's modulus.
@MFDOOMgr4 жыл бұрын
@@TheEfficientEngineer and practically this means? that this kind of material can take up to 210000 N / mm^2 and then breaks?
@TheEfficientEngineer4 жыл бұрын
No - it means that the slope of this material's stress-strain curve in the elastic region is equal to 210000 N/mm^2. So for example for an applied stress of 210 MPa, we would get a strain of 0.1%.
@whitelight324 жыл бұрын
@@TheEfficientEngineer Doesn't that also mean that we need 2.1 MN of force to change the materials area by 1 mm^2 ?
@gieaudio87624 жыл бұрын
@@whitelight32 no, it means that you need 210 GPa stress in material to deform it by 100%, of course it will fail because Young modulus is only appropriate (linear) in elastic range of the material. Simply saying, Young modulus is the number that helps you transform stresses to strains and vice versa but only in the elastic range of the material, for concrete it is 0,20% for compression, for reinforcing steel it is up to ~0.24% in tension

This is a really great straight forward video. As a Metallurgist, this was a really good introduction. You explained it way better than my professors did. I don't wanna be that guy that tells you why your video is wrong. But around 5:30, you show that carbon replaces the iron atoms in your model. In reality, carbon goes in between the iron atoms in the interstitial space. This is hopefully a video that you could do in the future talking about until cells and Crystal structures. Keep up the good work!

Thank you for your kind comments Jon. You are of course correct about the interstitial nature of steel - my mistake. Hopefully the animation still illustrates the point without being too misleading. A video on unit cells would be really interesting - thanks for the idea!
@a1mforthetop4 жыл бұрын
@pyropulse As an engineer with quite some work experience i must say the following: The stuff with the atoms is nice and everything but it should have been left out of a beginners introduction video entirely. The only thing that has to stick in the head of an efficient engineer is that E is a material constant that represents the slope of sigma and epsilon and is different for different materials. It is also commonly used in combinations like EI and EA. For the advanced theoretical engineer the atom part is important of course ;)

Just found your page tonight I find it interesting so far. I’m a dual ticket Red Seal Ironworker and Welder and I’ve performed tensile tests both in school and at work. What you covered is very informative but you could have added more about quenching and tempering and how much tensile strength it can add. How it increases brittleness and ductility. I had a weld test on mild steel with 7018 SMAW welding electrode(rated for 70000 psi per square inch) heated red hot and quenched immediately. It sheared at 138,000 psi on the tensile test which I found very interesting.

Correction if I may. 5:37 depicts the Fe atoms being replaced by Carbon, that's what happens in substitutional alloys. Steel is a interstitial alloy, the carbon atoms to not replace Fe atoms, instead they reside in the space between the Fe atoms. This is VERY important since the formation of martensite depends on the position of those C atoms to change the crystal structure of steel into BCT(body centered tetragonal)

Good video that I can recommend to my students. But be careful: in your stress-strain curve, you have greatly overestimated the elastic strain (it's just 0.1-0.5% for most steels) as compared to the plastic strains. Also, while many engineering materials indeed follow Hooke's law, this is by no means generic behaviour. Many plastics, foams, and biological matter are very different :-)
