Abstract
In this contribution we introduce a phase field model for fatigue crack growth. The model is based on a diffuse formulation of quasi static brittle fracture. In order to account for the fatigue phenomenon an additional energy contribution is incorporated. This additional component represents the amount of accumulated energy associated to irreversibilities of cyclic loading and unloading. The evolution of a fracture phase field is governed by an appropriate Ginzburg-Landau type equation. To enable efficient computation the integration scheme is transferred into the cycle domain. Finally, by showing results of different fatigue crack growth scenarios the model behaviour in terms of crack growth rate, mean stress effect and also growth direction is illustrated.
