Anisotropic wear framework for 3D contact and rolling problems

Abstract

This work presents a new methodology to compute anisotropic wear on 3D frictional contact and/or rolling problems. The damage on the solids’ geometries and the contact pressures evolution under anisotropic tribological properties can be predicted using this contact framework. The present formulation uses the Boundary Element Method and/or the Finite Element Method for computing the elastic influence coefficients, and enforces contact constraints using a new augmented scheme. An anisotropic wear model is considered, together with an orthotropic friction law. The methodology and the proposed algorithm are illustrated with some examples, in which different studies about the influence of anisotropy on wear are presented.
