Continuous dependence and optimal control of a dynamic elastic-viscoplastic contact problem with non-monotone boundary conditions

<p style='text-indent:20px;'>In this paper, we consider continuous dependence and optimal control of a dynamic elastic-viscoplastic contact model with Clarke subdifferential boundary conditions. Since the constitutive law materials has an implicit expression stress field, weak form is evolutionary hemivariational inequality coupled integral equation. By providing some equivalent formulations, prove solution on external forces initial conditions in topologies. Finally, existence solutions to problem established.</p>
