What is Front Tracking for Shear Bands in an Antiplane Shear Model about?

constraint. For this reason, the interaction of the tracked front with the underlying hyperbolic grid is nontrivial and In this paper we describe a numerical algorithm for the study of shear band, formation and growth in two-dimensional antiplane we develop techniques to allow for the growth of the shear shear. The constitutive model uses a non-associative flow rule. The band by more than one cell per time step. numerical scheme is based on a Godunov method for updating the In particular, the model used in this paper includes a velocity, while the stress is updated via integration along particle non-associative flow rule. Non-associative flow rules are paths. The scheme is coupled with a front tracking algorithm for recognized as an important tool in the modeling of deforcareful evolution of the shear bands. The main challenges are the non-hyperbolicity of the shear band formation and growth (front mations in granular materials (see Vardoulakis and Graf tracking avoids the catastrophic effects of the loss of hyperbolicity [21]). This present model has been studied by Schaeffer in the Godunov-type numerical scheme), the existence of endpoints [13] and offers a criterion for the form
