Abstract
The subject of this chapter is the application of the hybrid finite element method (FEM) to the evaluation of the actual shakedown residual stresses in a prismatic elastic-plastic body subjected to cyclic loadings. A preliminary model was presented in [[7.1]]. The formulation was further developed and was verified by comparison of numerical results from one-dimensional models with results from independent solutions [[7.2]], [[7.3]]. The revised formulation has now been extensively tested in a two-dimensional model of a prismatic body, and the new results have again been compared with the independent solutions. The two-dimensional model is essentially in the form required for analysis of a rail as a prismatic body, and some example calculations of rail residual stresses have also been performed.
