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:
