Decay rates of magnetoelastic waves in an unbounded conductive medium
Electronic journal of differential equations, Tome 2011 (2011)
We study the uniform decay of the total energy of solutions for a system in magnetoelasticity with localized damping near infinity in an exterior 3-D domain. Using appropriate multipliers and recent work by Charao and Ikekata [3], we conclude that the energy decays at the same rate as $(1+t)^{-1}$ when $t\to+\infty$.
