摘要：

In this paper, fatigue crack growths of surface cracks in structure have been simulated and residual life have been predicted by s-version finite element method on the basis of linear fracture mechanics. Fatigue crack growth of surface crack in plates under remote tension, bending or combined load is modeled. The relationship between a/c and a/t of different initial crack shape in the process of crack growth is examined. The law of crack shape change during the growth process is analyzed. The results indicate that load form has great effect on crack shape in growth and surface cracks of different initial shape have same growth law under same load.
