FEPX - Finite Element Polycrystal Plasticity

Overview

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
