Question

Find an expression for the energy density in terms of stress and strain.

Answer 1

Think of stress as bending as well as pushing down upon an object, where as strain is more like stretching a rubber band almost to its limit, and the stress of a bridge holding up. And we can easily find the expression for the energy density in the terms of stress and strain.so The expression for the energy density in terms of stress and strain can be expressed as ρe.
