Fracture propagation in a heterogenous medium

Fracture propagation in a heterogenous medium

Phase-field modeling of fracture and damage has become an extremely active research field since 1998 when G. Francfort and J.-J. Marigo proposed a variational fracture approach. In the last decade, applications in solid mechanics, porous media and multiphysics have been addressed. In this presentation,  ingredients will be explained in which I have been involved. These include treatment of crack irreversibility (the crack cannot heal), adaptive discretizations with finite elements, goal-oriented error control, predictor-corrector techniques to estimate the future crack path, and the robust-efficient numerical solution with nonlinear solvers (Newton-type) and linear solvers including multigrid preconditioning. Numerical tests with applications in civil engineering and porous media substantiate my developments.
