Abstract
Arbitrary Lagrangian–Eulerian ALE methods provide a well established basis for the numerical analysis of rolling contact problems Whereas the theoretical framework is well developed for elastic constitutive behavior special measures are necessary for the computation of dissipative effects like inelastic properties and friction because the path of material points is not traced inherently In this presentation a fractional step approach is suggested for the integration of the evolution equations for internal variables A TimeDiscontinuous Galerkin TDG method is introduced for the numerical solution of the related advection equations Furthermore a mathematically sound approach for the treatment of frictional rolling within the ALEdescription is suggested By this novel and fully implicit algorithm the slip velocities are integrated along their pathlines For dissipative effects due to both inelastic behavior and friction physical reliable results will be demonstrated as well as the computability of large scaled finite element tiremodels
