Strain energy is area under stress-strain curve. So how can it be within elastic limit? After yield point you will find area under stress-strain curve that means specimen has strain energy.

Take a example of a spring so when you elongate it within elastic limit (i.e point till which it can regain its original shape and size) by doing so strain energy is stored.

We know that area under the stress-strain curve up to to the elastic point is called strain energy.

" Within Elastic Limit Stress is directly proportional to stress" So, the energy stored in the body when strained.
Ex. Spring.

It's by definition that stain energy stored in a body is within elastic limit. Yeah there will be some more strain energy after elastic limit. But as after elastic limit body can't regain back it's original position and so we do not consider that energy. Because after yielding point body is said to be failed.

Strain energy is energy stored in a body while an external force applied under elastic limit.

How strain energy is measured?

Strain energy stored up to elastic limit is called proof resilience.
And area under stress-strain diagram after yield point is called strain hardening.

Strain energy is the energy which is elastically stored within a body.
