Abstract

This work presents the results of a finite element analysis (FEA) which is used to simulate twodimensional

(2D) sliding between a rigid/hard cylinder on an elastic-plastic cylinder. The material for the top cylinder is modeled as rigid, and the bottom cylinder is modeled as elasticplastic and follows the von Mises yield criterion. The finite element software, ANSYS, is used to analyze the deformations, reaction forces, and stresses on the lower cylinder. The mesh was refined in the contacting area in order to achieve the convergence. The FEA provides trends in the deformations, reaction forces, and stresses as a function of the interferences and sliding distance between the cylinders. Results are presented for both frictionless and frictional sliding and comparisons are drawn. The formation and distribution of stresses along the sliding

distance are presented in von Mises stress contour plot. Result show that for the plastic loading case the ratio of the horizontal force to the vertical reaction force is zero at the point where the cylinders are perfectly aligned about the vertical axis. The loading and unloading phenomena between two interfering cylinder is performed.
