A Newton method for three-dimensional fretting pr

The present paper concerns the numerical treatment of fretting problems using a _nite element analysis[ The governing equations resulting from a formal _nite element discretization of an elastic body with a potential contact surface are considered in a quasi!static setting[ The constitutive equations of the potential contact surface are Signorini|s contact conditions\ Coulomb|s law of friction and Archard|s law of wear[ Using a backward Euler time discretization and an approach based on projections\ the governing equations are written as an augmented Lagrangian formulation which is implemented and solved using a Newton algorithm for three!dimensional fretting problems of didactic nature[ Details concerning the implementation are provided
