How do you calculate the area under the stress-strain curve?

1.	How do you calculate the area under the stress-strain curve?
Answer» The toughness of an object is the amount of energy per unit VOLUME that a MATERIAL can absorb without fracturing. Method of toughness calculation is- Find the area under a stress-strain CURVE that has to be DRAWN for that material. It is calculated by integration of the curve. It is one of the most common Mechanical engineering Interview Questions.
