In this video I introduce the quantities of ductility (plastic strain to fracture), toughness (energy absorbed to fracture) and resilience (elastic energy stored at yield strength).
@@Maedetto You might not have a discreet equation for data like this, in which case a numerical integration approach like simpson's rule or the trapezodial rule could be used to approximate the integral. Just choose your n-value to be sufficiently large enough to get a good resolution of the integral and better accuracy through the numerical method.
i think the Hooks law only validatee in linear region or say elastic region
No not in all of the elastic region hooks law is only valid till the proportionality limit
How i calculate the modulus of thougness for the given stress - strain diagram?
I don't understand how you calculate the area under the curve to get toughness. Could someone explain?
I believe is a definite integral. However, you need an equation for the line on the graph in order to be able to calculate it.

I would simply do a numerical integral approximation after graphing a rough sketch. Python would be good for this.
Very helpful video. Thank you!
What is difference between strain energy and resilience?
Thanks! This helped a lot.
Excellents videos. Congratullations!!!!!!!!!
Thank you sir, I've got the idea regarding what ductility is.
When you say unloaded the strength what excatly it means?
Jatin Pachpend I think he meant the load.
thanks from turkey
Good
Thank You
I think you are confusing ductility with elasticity.
Engineering 2T1!!!
Thank you very much. It is more than what I expected.
what the hell is this :/
