DYNAMIC FAULT RUPTURE AND PROPAGATION THROUGH A FIXED FINITE ELEMENT GRID

Liu, Fushen / Borja, Ronaldo I.

Summary The extended finite element method is used to simulate dynamic fault rupture in elastoplastic solids. Rupture is governed by a linear slip-weakening law and finite element calculations are done explicitly. In a numeric example, we study a benchmark problem comparing the new technique with conventional finite element simulations, including the regular penalty formulation and split-node technique for rupture propagating with off-fault bulk plasticity.
