Hydro-mechanical fracture modeling governed by topological derivatives
2020
Abstract The process of fluid-driven crack propagation in permeable rocks is investigated by a simple hydro-mechanical model and the concept of topological derivative. Analytical and numerical computations are made to propose a promising model tested and validated on a series of bidimensional benchmark examples. The main guidelines for this model are the use of simple finite elements with a minimal number of user-defined algorithmic parameters.
