Resum

Phase-field models for brittle fracture consider smeared representations of cracks, which are described by a continuous eld that varies abruptly in the transition zone between unbroken and broken states. Computationally, meshes have to be ne locally near the crack to capture the solution. We present a Hybridizable Discontinuous Galerkin (HDG) formulation for a quasi-static phase-field model, based on a staggered approach to solve the system. The use of HDG for this model is motivated by the suitability of the method for adaptivity.

Keywords: phase-field, staggered scheme, brittle fracture, hybridizable discontinuous Galerkin (HDG).
