- 摘要：Fatigue life and crack growth retardation due to spectrum loading, which are superposed on constant amplitude cycles, have been investigated in this paper. For this purpose, numerical and experimental methods are used to investigate the behavior of fatigue crack growth in the rail specimens. A 3D nonlinear boundary element model has been applied to estimate the fatigue life of the rail specimens. Then, the effect of several parameters on the fatigue life in rail specimens is investigated using the suggested 3-D boundary element model and experimental tests. In the numerical analysis, the ...
