Elastic modulus describes the stiffness of a structure due to the material. Here's a clear explanation and an example. Check out the whole PurdueMET Channel at: / purduemet

Hello, Professor! In this case, you are bending the material as opposed to the conventional compression or elongation used to obtain the stress-strain curve. Generally speaking, will the trends that we see here for bending be the same when compressing a material? I have recently started working with molecular crystals that researchers have labeled as elastic when they regain their original shape after bending, but I am not sure if the terminology is the same. Please let me know what you think. P.S.: this is a great video. Thank you for making it so simple to comprehend!
@mecanicoing9 Жыл бұрын
Good introduction to E. Two questions, what is the relationship between E and the temperature of the material? And when doing stress calculations should we use the E at ambient temperature or at the design temperature and why? What is the proper approach?

Thank you for this wonderful explaining, but I got a question If we are doing a tensile test and a compressive test to the same material with another Rod, Will the Elastic Modulus be the same at the two different tests?
@purdueMET3 жыл бұрын
Yes, elastic modulus is the same for tension and compression. This assumes there's no permanent deformation.

Difference between modules of elasticity and modules of rigidity and Bulk modulus and poison ratio..?
@staticentropy68223 жыл бұрын
the thing that I can't quite get is this...knowing the fact that "E" is stress over strain...that should mean that if we have the strain and E we should be able to calculate mathematically the stress that was responsible for that strain....now does that mean that if we had strain caused by Tension we could find the stress that caused it using the Elastic Modules, and if we had the Strain caused by compression we could find the stress using the same modules (EX:210Gpa)....or does E for Tension deffer from E for Compression....and in bending is where it gets really complicated for me.....because in bending there are 2 stress's...so which one are we finding....and can we actually accurately calculate stress or strain using the Elastic Modules knowing that is another stiffness that is coexisting with the material stiffness which is the shape stiffness....too many questions...I don''t know...there must be something that i'm missing or not understanding correctly

Great video, but it is missing a final 😀Why does everyone, yes EVERYONE "fail" to explain from WHERE this huge value comes from? How is it defined/tested/calculated for let's say a brand-new unknown material? How does this number define the stress/strain elastic angle?

Did not explain what the numbers actually mean! It could be better if you add that for the same strain to generate in each of material, you need that much stress.

It might be beneficial to explain that "modulus" means "a constant or coefficient that expresses, usually numerically, the degree to which a body or substance possesses a particular property (such as elasticity)".
