In this article we studied the stability and regularity of a beam of length l composed of viscoelastic material in two situations: in the first, we consider the beam fixed at its ends; and in the second, the beam supported at its ends. The system is governed by an Euler-Bernoulli beam model with Kelvin-Voight type damping. We will use the Semigroup Theory to prove the existence and uniqueness of solutions, and the Pruss result to study the asymptotic behavior of the solutions of both models. Furthermore, we showed the loss of analyticity for the second model, which is also a relevant result, as it shows that the solutions are not analytical functions in relation to the time variable.
