Numerical Simulation of Strike-Slip Faults Based on Slip Weakening Friction Law

This paper describes the three-dimensional numerical modeling of a vertical strike-slip planar fault that resides in the crust and reaches the Earth's surface. The goal of this study is application of a constitutive relation which represents the governing equation of the failure process and specifies the dependence between stress, fault slip, slip rate, and other relevant physical properties. There are several laboratory-derived friction constitutive laws among which the linear slip-weakening was adopted in this paper to simulate the failure process based on stick-slip instability of faults. The finite element code (ABAQUS) is used to model the mechanical behavior of fault illustrating the distribution of stress and deformation in the Earth’s crust which involves the fault.
