Abstract
This work analyzes the influence of friction on the surface and subsurface contact stresses generated—in an elastic half-space—by a cylindrical flat-ended punch. For this purpose, the computational framework presented by [J. M. Juliá and L. Rodríguez-Tembleque, Subsurface stress evolution under orthotropic wear and frictional contact conditions, Int. J. Mech. Sci. 234 (2022) 107695] is extended to solve this problem. After the validation of this computational scheme, several numerical studies have allowed us to obtain the following conclusions. (i) The location of the maximum values of the subsurface Von Mises stresses in the [Formula: see text]–[Formula: see text] plane does not depend on the friction coefficient and is located at the contact zone limits — similarly to the normal pressure — (ii) However, the [Formula: see text]-location and the magnitude of the maximum value of the subsurface Von Mises stress is clearly affected by the values of the friction coefficient. (iii) The magnitude of the maximum value of the subsurface Von Mises stress increases and its location can be shifted from the subsurface region to the solid surface, when the friction coefficient increases its value.
