We study the asymptotic behavior of the solutions of a 3-D hyperbolic system arising in linear homogeneous anisotropic thermoelasticity with a dissipative boundary condition with memory for the displacement. By introducing a boundary free energy, we prove that, if the memory kernel exponentially decays in time then also the energy exponentially decays.

Abstract
We study the asymptotic behavior of the solutions of a 3-D hyperbolic system arising in linear homogeneous anisotropic thermoelasticity with a dissipative boundary condition with memory for the displacement. By introducing a boundary free energy, we prove that, if the memory kernel exponentially decays in time then also the energy exponentially decays.File in questo prodotto:
