Modeling of anisotropic surfaces within a covariant contact description

Within covariant contact descriptions all necessary characteristics, such as kinematics of deformation and the weak form, as well as all necessary operations, such as linearization and derivation of the finite difference scheme, are described in the specially defined local surface coordinate system, which is related to the closest point projection procedure. This description allows to generalize all contact characteristics into an anisotropic domain for both adhesion and sliding behavior in a straightforward form. The model can be used to describe the average behavior of machined surfaces. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
