Abstract
An 3D elastic-plastic rough contact solution and code is developed using a modified semi-analytical method. It is supposed that the total surface deflection is induced by the contact pressure and plastic strain. The purely elastic contact and the influence of the plastic deformation are calculated iteratively until convergence is satisfied. The distributions of contact pressure, residual stress and plastic strain are obtained through simulation. The effects of roughness and plastic hardening upon the pressure distribution are discussed.
