We develop a new numerical method for simulating three-dimensional elasto-plastic materials in the slow, quasi-static limit. Large-scale simulations are performed in parallel, and make use of a custom multigrid solver to enforce the quasi-staticity constraint. We test the method using an elasto-plastic model of a bulk metallic glass based on the shear transformation zone (STZ) theory. By applying simple shear to heterogeneous samples, we explore and statistically characterize the dynamics of shear band growth.
