FEPX is a parallel finite element-based elasto-viscoplastic framework for use in modeling large deformations of polycrystalline aggregates. Its primary features are:
- Nonlinear kinematics capable of resolving large strains and large rotations
- Anisotropic elasticity based on crystal symmetry
- Anisotropic plasticity based on rate-dependent slip restricted to dominant slip systems
- State variable evolution for crystal lattice orientation and slip system strengths
Installation instructions for FEPX are provided in the PDF documentation included in the distribution.
