Modelling of the mechanical behaviour of active geological faults using a poro-plastic hardening/weakening interface constitutive law

The code and datasets published on this repository are the supplementary materials of the two JGR articles : CP1: Conditions for triggering seismic ruptures and/or slow slip events, V. Maury, J.-M. Piau, D. Fitzenz CP2: Interface plastic constitutive law with end-cap and structural model applied to geological faults behavior, J.-M. Piau, V. Maury, D. Fitzenz These papers deal with the mechanical behaviour of active geological faults submitted to far-field displacements. The study is based on the development of a poro-plastic hardening/weakening interface constitutive law sandwiched between two elastic pads. Despite its current simplicity useful to derive semi-analytical computations, the model manages to reproduce the sequence of stable quasi-static phases and unstable dynamic phases, depending upon the data (initial stress field, far-field displacements, fault drainage condition,...).
