We have utilized a statistical method to model the shear behavior of rough contacts. In contrast to the traditional statistical methods, which only describe the asperity height and curvature distributions, we have introduced a contact orientation distribution in our analysis. We have also incorporated asperity contact sliding and developed an incremental scheme for computing the stress-displacement relationship. Using this enhanced model, we can demarcate the boundary between elastically deforming and sliding asperity contact orientations under given loading. Consequently, we can describe the shear-normal coupling as well as the effects of inherent anisotropy and the induced anisotropy of the sheared interfaces.
