The present study deals with the solution of the fully three‐dimensional contact/friction problem taking into account microstructural characteristics of the surfaces. An incremental non‐associated hardening friction law model analogous to the classical theory of plasticity is used. Two different non‐linear friction functions in the orthogonal directions are used to account for the orthotropic properties of the contacting bodies. A frontal solver processing unsymmetric matrices is adopted. Two numerical examples have been selected to show applicability of the method proposed. © 1997 by John Wiley & Sons, Ltd.
