Abstract

The simulation of 3D fatigue crack propagation in terms of linear elastic fracture mechanics is presented. Due to the non-linear behaviour of crack growth an incremental procedure has to be applied. In each increment three steps have to be performed: aa complete stress analysis including the calculation of the fracture mechanical parameters, bthe determination of the new crack front by the evaluation of the 3D crack growth criterion and cthe update of the numerical model for the next increment. In the present work special attention is focused on the continuous change of the stress field between two successive crack fronts that is considered by the implicit time integration scheme in terms of a predictor-corrector-procedure.
