摘要

A method for determining the limiting state of elastic half-spaces with a groove after fretting wear, under complete contact and subjected to alternating-sign shear forces, is developed. The limiting stress of bodies after the end of wear through the initial shape of the groove, and the thickness function of the worn material in the slip zone, is given. The singular integral equation with a Cauchy kernel is written, and its analytical solution is obtained to determine the thickness function of the worn material. The limiting shape of the groove and the contact pressure after wear for different values of shear loads, Poisson’s ratio, and the width of the wear zone are analyzed.
