摘要：

This paper presents a numerical concept far fatigue crack propagation computations, within the theory of the finite element method and the theory of linear elastic fracture mechanics, capable of automatic analysis of curved 3-D crack fronts and non-planar crack surfaces. The general modelling of fatigue crack growth and the present algorithm based on a remeshing technique are described. A comparison to existing analytical solutions for an embedded elliptical crack shows satisfying agreement and a fatigue crack growth analysis of a real-life component illustrates the framework applicability.
