Modeling of Fracture in Polycrystalline Materials

authored by: Steffen Beese, Stefan Loehnert, Peter Wriggers
Abstract: Predicting the behaviour of fracture processes within polycrystalline microstructures will help to develop more accurate mesoscale material models and will give insight to effects which can only be measured ex-situ. Therefore a non-local damage model is introduced and coupled to finite deformation crystal plasticity. Cracks are represented sharply by using the extended finite element method in combination with level set techniques. As damage evolves cracks start to propagate. A new crack propagation algorithm is presented and studied by academic examples.
