Micro Abstract:
A phase field model for interface failure between two materials is proposed where the interface is incorporated by a local reduction of the critical fracture energy. Due to the use of a regularised crack model, interaction between the length scales of the crack and the material interface has to be analysed. A local approach is presented, that compensates the influence on the actual numeric fracture toughness at which the crack propagates along the interface.
