Abstract
In this work we present an inversion framework to identify material properties defining the plastic behaviour of pore collapse modeled by thermo-hydro-mechanical simulations. This framework is built on the finite element REDBACK numerical simulator, which is capable of solving a multi-physics problem in a tightly coupled, massively parallel manner. We demonstrate the approach by matching the stress-strain response of an Adamswiller sandstone in a drained triaxial experiments.
