Nonstationary Lame system without definite sign energy

This article concerns the existence and decay of solutions of a nonstationary Lame system. This system has a nonlinear perturbation that produces an energy without definite sign. We consider displacement and traction conditions at the boundary and a general nonlinear boundary damping. We also obtain...

Description
Summary:This article concerns the existence and decay of solutions of a nonstationary Lame system. This system has a nonlinear perturbation that produces an energy without definite sign. We consider displacement and traction conditions at the boundary and a general nonlinear boundary damping. We also obtain exponential decay of the energy.
