Abstract

This work is devoted to the numerical study of a composite under dynamic contact with friction loading, known as tribological loading. A dynamic explicit finite element model is used and Lagrange multipliers allow determining the local forces due to contact and friction. The convergence of numerical contact with friction models, achieved by using a regularized Coulomb friction law, is presented first. This study also shows the equivalence between the results obtained with heterogeneous and homogeneous materials under dynamical tribological loading. The homogeneous models are built by calling on classical homogenization theory because the main wavelength of the loading is much higher than that of the heterogeneities and the contrast between elastic properties is low.
