| Abstract |
In this paper, we are concerned with the stabilization of a laminated beam with one discontinuous local internal fractional damping. We reformulate the system into an augmented model and prove the well-posedness of it by using semigroup method. Based on a general criteria of Arendt-Batty, we show that the system is strongly stable. By combining frequency domain method and multiplier techniques, we establish a polynomial energy decay rate of type t−2/(1−α) for the case of equal wave speeds, and obtain a polynomial decay rate of type t−2/(5−α) when the wave speeds are different. |
