VUANISOHYPER_STRAIN

User subroutine to define anisotropic hyperelastic material behavior based on Green strain.

User subroutine VUANISOHYPER_STRAIN:

  • can be used to define the strain energy potential of anisotropic hyperelastic materials as a function of the components of the Green strain tensor;

  • will be called for blocks of material calculation points for which the material definition contains user-defined anisotropic hyperelastic behavior with Green strain-based formulation (Anisotropic hyperelastic behavior);

  • can use and update solution-dependent state variables;

  • can use any field variables that are passed in; and

  • requires that the values of the derivatives of the strain energy density function be defined with respect to the components of the modified Green strain tensor and the volume ratio.
