Material fracture due to deformation caused by contact that changes with time is a complex phenomenon. Here, we use numerical simulations with the phase-field approach to study crack propagation in several contact problems, such as cutting problems and arch collapse. FreeFEM with the IPOPT package is very useful for analyzing problems with such inequality constraints.
