Abstract :
The interaction of acoustic waves with submerged structures remains one of the most difficult and challenging problems in underwater acoustics. Many techniques such as coupled Boundary Element (BE)/Finite Element (FE) or coupled Infinite Element (IE)/Finite Element approximations have evolved. In this paper, we focus on the steady-state formulation only, and study a general coupled hp-adaptive BE/FE method. The work is devoted to a study on viscoelastic scattering problems in linear acoustic medium by means of hp boundary and finite element approximations. A particular emphasis is placed on an a-posteriori error estimation for the viscoelastic scattering problems
