# UHYPER

 User subroutine to define a hyperelastic material. User subroutine UHYPER: can be used to define the strain energy potential for isotropic hyperelastic material behavior; is called at all material calculation points of elements for which the material definition contains user-defined hyperelastic behavior; can include material behavior dependent on field variables or state variables; and requires that the values of the derivatives of the strain energy density function of the hyperelastic material be defined with respect to the strain invariants. The following topics are discussed:
