Numerical simulation data and FORTRAN code to compare the stress response of two transversely isotropic hyperelastic models
We presented the numerical simulation data obtained by implementing a user material subroutine UMAT in the finite element commercial package ABAQUS. The simulation data correspond to the stress response of two transversely isotropic hyperelastic models on homogeneous and non-homogeneous deformations. The first model is the Holzapfel-Gaser-Ogden (HGO) model that only depends on the anisotropic invariant I ̅_4 for the description of the fiber reinforcement. The authors propose the second model that relies on both anisotropic invariants (I ̅_4 and I ̅_5). Since the proposed model is not found in the ABAQUS material library, we presented a FORTRAN code for a user-defined material subroutine UMAT. In addition, we introduced in detail the steps to implement the material models using the attached files in ABAQUS.
Steps to reproduce
INP, ODB, and FORTRAN files are provided to run simulations on ABAQUS
