✦ Synopsis

The effects of boundary conditions and mesh refinement of finite element models of elasto-plastlc 2-dimensional pure rolling contact are examined. The pure rolling of a cylinder is simulated by incrementally translating a semi-elliptical Hertzian pressure distribution over a finite element model of a semi-infinite half space. The half space is treated as an elastic-linear-kinematic-hardening-plastic (ELKP) material. The calculations evaluate the effects of rigid and elastic boundary conditions and two degrees of mesh refinement on the steady state residual stresses, the continuing cyclic plasticity, and the residual displacements. The results show that the boundary conditions influence the circumferential residual stresses and residual displacements, while they do not affect the axial residual stresses and the continuing cyclic plasticity. Careful choice of mesh refinement is shown to improve results and decrease computation time.

The cold rolling of rectangular section slabs is analysed for a range of width-to-height ratios (one to three) for which spread of the workpiece is appreciable. This necessitates the use of a three-dimensional model. An elastic-plastic finite-element method is used to provide a complete description
