The new Geomechanics Module is a specialized add-on to the Structural Mechanics Module aimed at modeling and simulating applications in geomechanics and rock mechanics. The Geomechanics Module includes tailored material models to study plasticity, deformation, and failure of soils and rocks, as well as their interaction with concrete and human-made structures.
