Abstract
The analysis of discontinuities in geological modelling requiresspecialized numerical techniques.In the present work, zero-thickness interface elementsof the Goodman type are usedin the context of the FEM. Due to the potentially strong interactionbetween the solidand fluid phases, a fully coupled (monolithic) hydro-mechanical formulation[1]is proposed for the analysis of hydraulic fracture.One of the key points of current investigation is the mechanical constitutive law. In this paperan elastopl...
