|Abstract:|| We deal with the Ambrosio-Tortorelli approximation of the well-known Mumford-Shah functional to model quasi-static crack propagation in brittle materials.
We employ anisotropic mesh adaptation to efficiently capture the crack path.
Aim of this work is to investigate the numerical sensitivity
of the crack behavior to the parameters involved in both the physical model
and in the adaptive procedure.|
