Abstract: This paper proposes a framework for the mesoscale modeling of potentially complex fault cores. Such faults cannot be modeled as simple frictional interfaces because they may be thicker and made of several slip surfaces embedded in a material that can contain both grains and broken blocks. Two main aspects are considered here. One, which is the main innovation in the paper, deals with the derivation for the specific rigid‐plastic interface constitutive law which was developed to account for the hardening/soften…
