The Rao–Nakra sandwich beam models under study in this paper consist of coupled two wave equations and one Euler–Bernoulli equation on an open bounded interval of R subject to homogeneous Dirichlet–Neumann boundary conditions. The objective of this paper is to investigate the well-posedness and asym...
