Analysis of the frictional slip between a layer and a half-space R. Abascal, J. Dommguez Escuela Superior de Ingenieros Industrials, Universidad de Sevilla, Av. Reina Mercedes, s/n, 41012-Sevilla, Spain ABSTRACT The numerical analysis of a boundless elastic layer on an elastic half- space with different material properties under the effects of an uniform surface pressure and a cyclic tangential surface force is presented. Frictional contact conditions are assumed. The study is focussed on the evaluation of the maximum amplitude of the tangential load which produces localized slip between the two regions during the first load cycle but not the subsequent ones. The more simple limit for which no slip exist even for the first cycle is also established INTRODUCTION The study of the slip and separation that may take place between two surfaces in contact when they are under tangential cyclic loading conditions is very important to prevent the failure k
