Abstract: 
 In this work we study the asymptotic behavior of solutions of a
 dissipative plate equation in $\mathbb{R}^N$ with periodic
 coefficients. We use the Bloch waves decomposition and a
 convenient Lyapunov function to derive a complete asymptotic
 expansion of solutions as $t\to \infty$. In a first
 approximation, we prove that the solutions for the linear model
 behave as the homogenized heat kernel.
