Parameter study on a phase‐field model for fatigue fracture

Abstract

Recently, the problem of modelling fatigue fracture has been approached by the phase-field method. The approach of Seiler et al. [1] focusses on a reduction of computational cost by combing the phase-field method for fracture with a classic fatigue concept. For this model, we perform a parameter study analysing the influence of the fatigue degradation function and the crack propagation behaviour under cyclic loads with different mean loads. Eventually, we compare the results to a cyclic compact tension test.
