Abstract

This paper presents a method, which may be used to determine residuaI stress distribution in bodies subject to cyclic loads. A mixed global/local version of the Meshless Finite Difference Method (MFDM) is used to devise a discrete computational formulation of a shakedown based residual stress calculation mechanical model for elastic-plastic bodies subject to cyclic loadings. Several 1D and 2D verification/vaIidation tests are presented, including thorough discussion of results and conclusions regarding the details of computational model. The method developed is applied to determine residual stress distribution in a railroad rail subject to simulated contact load.
