Effect of loading induced anisotropy on the shear behavior of rough interfaces

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 incorporat...

Summary: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. ► Contact orientation distribution introduced into statistical multi-asperity method. ► Method includes elastically deforming and sliding asperity contacts in shear. ► Method describes the shear-normal coupling of the sheared interfaces. ► Includes the effects of inherent and induced anisotropy under shear.
