We describe a numerical algorithm for the study of shear band formation and growth in two-dimensional antiplane shear. The constitutive model uses a non-associative flow rule. The numerical scheme is based on a Godunov method for updating the velocity, while the stress is updated via integration along particle paths. The scheme is coupled with a front tracking algorithm for careful evolution of the shear bands. We give examples of the success of the algorithm and show convergence tests.
