FEPX: Finite Element Polycrystal Plasticity


FEPX is a finite element software package for polycrystal plasticity. It can model both the global and local mechanical behaviors of large polycrystalline aggregates with complex microstructures via a scalable parallel framework.


See also FEPX’s companion program, Neper, a polycrystal generation and meshing tool. Neper acts as the primary pre- and post-processor for FEPX.

FEPX is currently maintained and developed by the Advanced Computational Materials Engineering Laboratory ACME Lab at The University of Alabama.
