| dc.description.abstract | The variational and numerical study of some contact problems with or without friction, between a deformable body and a foundation. Here we consider nonlinear laws of behavior for viscoplastic materials. For these problems we obtain variational formulations followed by existence and uniqueness results of weak solutions. The techniques employed are based on the theory of monotone operators followed by a version of the Cauchy-Lipschitz theorem and Banachís fixed point arguments. Finally, we propose a numerical approximation of the purely mechanical problem using discrete schemes. For these schemes, we obtain error estimation results | |
