Simulation of orthotropic frictional contact with non-associated sliding rule

Résumé

For many industrial applications, the assumption of isotropic friction is unrealistic because of directional surface machining and finishing operations. For orthotropic frictional contact, Michałowski and Mróz pointed out the non-associated nature of the sliding rule. In the present work, their law is derived from a single non-differentiable function, called a bi-potential. On this ground, the time-integration of the contact law takes the form of a predictor/corrector scheme addressing all cases (sticking, sliding, no-contact) thanks to a projection onto the friction cone. 3D numerical applications show the strong influence of the slip rule.
