Simulation of Densification in Granular Materials and Geomaterials•An implicit formulation of a three-invariant, isotropic / kinematic hardening Cap plasticity model was programmed into ANSYS V10as a user material subroutine (usermat3d.f)
•Based on Foster, et al. (2005) with corrections and a few mods.
•Used to simulate behavior of rocks, ceramics, sand, soil, powders, etc.
•Single element tests
•Simulated multi-element hydrostatic & triaxial test samples
