Question

The area under stress-strain graph is?

Answer 1

Answer:

The material toughness can be expressed as the work W required to strain a bar to engineering strain ε. Thus, the area under the engineering stress-strain curve is a direct measure of the amount of work per unit volume of the material needed to effect a given engineering strain ε.

Answer:

The material toughness can be expressed as the work W required to strain a bar to engineering strain ε. Thus, the area under the engineering stress-strain curve is a direct measure of the amount of work per unit volume of the material needed to effect a given engineering strain ε.
