Potential for Strain energy

Hi all,

When a conservative force does work, it is independent of the path, we define the potential and work done is given by  - (change in potential).

We define potentials for gravitational force, electrical force etc...

Assuming the body is linear elastic, internal forces, cause stresses in a body, are also conservative forces, whose work (strain energy) is independent of the path. Can we define potential for such internal forces? If so, we can calculate strain energy = -(change in potential).

You may kindly explain this.

Thanks in advance,

With regards,

Strain energy density function

Would this be the strain energy density function which forms the basis of hyperelasticity?

I am speaking from linear elastic materail point of view. The strain energy of this material per unit volume gives the strain energy density.
