Abstract

A computational technique for the stressed state of a region lying beneath a rough solid surface is proposed. The calculation relies on the solution of a system of Laplace's equations for thin-walled shells and of an energy equation of deformation. Based on experimental data, a Gaussian bearing curve is chosen as a rough surface model. An analytic expression for the dependence of equivalent stresses and strain energy on the shape of the rough surface is derived.
