000015251 520__ $$2eng$$aFaults often separate materials with different elastic properties. Understanding dynamic rupture along bi-material interfaces is therefore a challenging issue for earthquake source dynamics. Numerical simulations of inplane rupture dynamics along a frictional bi-material interface were performed using the non-smooth Spectral Element Method (SEM) to investigate the coupling between shear strength and normal stress perturbations during non-stationary rupture propagation. In particular, we analyse numerically slip-weakening friction regularization, in which the shear strength evolves continuously with time in response to an abrupt change of normal traction, both during the acceleration and the asymptotic stationary phases of the rupture. This leads to a re-formulation of this regularisation and to propose an extension in terms of a non-local regularization model with a dynamic length scale that is shown to scale as the cohesive zone.
