We study behavior of the energy for solutions to a Lame system on a bounded domain, with localized nonlinear damping and external force. The equation is set up in three dimensions and under a microlocal geometric condition. More precisely, we prove that the behavior of the energy is determined by a solution to a forced differential equation, an it depends on the L^2 norm of the force.
