  In this paper we will study the asymptotic behaviour of the energy decay of a
transmission plate equation with force and moment feedback. Precisly, we shall
prove that the energy decay at least logarithmically over the time. The method
consist to use the classical second order Carleman estimate to estabish a
resolvent estimate which provide by the famous Burq's result [Bur98] the kind
of decay above mentionned.
