A transmission problem involving two Euler-Bernoulli equations
modeling the vibrations of a composite beam is studied.
Assuming that the beam is clamped at one extremity, and resting on an elastic
bearing at the other extremity, the existence of a unique global solution and
decay rates of the energy are obtained by adding just one damping device at the end
containing the bearing mechanism.
