11 writing ~q. where VB is, by definition, the virtual work of the stress per unit mass, show that Hence prove that VB is an exaet differential vB = ~u, if and only if, T ~(J is an exaet differential. When it exists the function u is ealled the strain energy density per unit mass. 13. In the notation of Ex. 12 show that astrain energy density exists if either T = eonstant, isothermal deformation, or ~(J = 0, adiabatie deformation. 14. Prove that the strain energy function is whether the material is isotropie or not.
