Solution of viscoelastic scattering problems in linear acoustics using hp boundary/finite element method

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.
