Strain energy density function

A strain energy density function is a model describing a hyperelastic material. The function relates the energy stored in an elastic material, and thus the stress-strain relationship, only to the three strain (elongation) components, thus disregarding the deformation history, heat dissipation, stress relaxation etc. Examples of strain energy density functions are the Neo-Hookean, Mooney-Rivlin and Ogden models.
