Nice presentation and lots of info. However surely (not blaming the prof as it is tradition but) elastic modulus E is a horrid name as it really represents stiffness. Rubber has very low E and concrete high E. Taking the reciprocal (1/E) is elasticity . Perhaps better to use symbol Y for young modulus or S for stiffness or whatever. This has been going on for hundreds of years, no wonder people get confused.
hi tx for ur video.. i have question.regarding true plastic strain and stress up to which point we need to enter data for simulation in abaqus?is it fracture point or ultimate point?
In mathematics,we usually plot the known values in horizontal axis and plot their corresponding values vertical axis.why here in this diagram we do the opposite?
This is a GREAT question! I agree that generally, the independent variable is on the horizontal axis. In fact, when we use a stress-strain diagram to predict "How much does a material deform under some load", this is exactly what we do. However, when we generate data for a stress-strain diagram, we generally control elongation (strain), and measure stress (using a load cell). So, in effect we come at it the other way. Stress-strain is a bit unique in that regard, as sometimes we treat either one variable or the other as the independent variable.

SOOOOO CLEAR!!! i love using your lectures to reinforce what i am learning in class thank you for all your hard work.
No words can express how I appreciate you for what you have done. Thank you so much!
Related toughness with the weights, are they intentionally destroying it to see what the failure mode is?
really i need some doctors explaining dental stuffs like this doctor it's hard to me to studdy

Thank you sir...its very useful....
thanks Dr
