摘要：

Fatigue crack growth is modelled by an improved step-by-step finite element technique for a shallow and long surface crack in a finite thickness plate under different combinations of tension and bending loads. The predicted crack shape development is presented for growth through the plate thickness and the shape compared with the widely assumed semi-elliptical profile. The predictions of the present simulation technique for the aspect ratio and the number of crack growth cycles are compared with those obtained both by Newman and Raju's method, and experimental results for aspect ratio changes taken from the literature.
