- 摘要:In this paper, a reliability analysis of fatigue crack growth for a pearlitic Grade 900A rail steel subject to the growth of multiple cracks is presented. The stress intensity factors (SIFs) at the tip of the cracks, by considering all possible combinations of all different cracks, are calculated by the boundary element method (BEM). A 3D boundary element analysis model has been applied to estimate stress intensity factors of the rail under the influence of cyclic loading conditions. For this purpose, an UIC60 rail with accurate geometry is studied. Paris Equation is used as a criterion of...
