AB  - A new finite element procedure is developed for theanalysis of sliding contact problems involving spatially varying coefficient offriction. The problem is implemented using APDL (ANSYS Parametric DesignLanguage) considering the Augmented Lagrange method as the contact solver. Upondiscretization of the contact interface into multiple contact pairs, a sequenceof steps is followed to evaluate the resultant friction force required for thesliding contact. As a case study, heterogeneous-friction contact problembetween an orthotropic laterally graded half-plane and a rigid flat stamp isinvestigated under plane strain assumption. The proposed iterative procedure isproved reliable by comparing the results to those generated by a SIE (SingularIntegral Equation) approach for isotropic laterally graded half-planes. Extraresults are presented to reveal the effects of problem parameters on thecontact stresses and the friction force. The paper outlines a convenientnumerical solution for an advance sliding contact problem, and the results canbe used in validation purposes of experimental and analytical studies.
