On models of contact surfaces including anisotropy for friction and adhesion and their experimental validations (original) (raw)

A numerical model for anisotropic contact interfaces including adhesion and friction is discussed and illustrated by numerical examples. Particular attention is paid to the validation of the proposed model via experiments, where the influence of the anisotropic interface on a path of a sliding block is checked. It is shown that with the classical orthotropic Coulomb type friction model some particular kinematic effects cannot be included, while the proposed orthotropic adhesion-orthotropic friction interface model allows to qualitatively describe the observed phenomena.
