Analysis of Fatigue Crack Propagation in Rails under Combined Action of Wheel Load and Residual Stress
TL;DR: In this article, a three-dimensional elastic-plastic finite element model of wheel-rail contact is established, in which a threedimensional oblique crack is inserted in the rail, and the effect of residual stress on fatigue crack propagation of rails is quantitatively analyzed.
