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

摘要

The interaction of acoustic waves with submerged structuresremains one of the most difficult and challenging problems in underwateracoustics. Many techniques such as coupled Boundary Element (BE)/FiniteElement (FE) or coupled Infinite Element (IE)/Finite Elementapproximations have evolved. In this paper, we focus on the steady-stateformulation only, and study a general coupled hp-adaptive BE/FE method.The work is devoted to a study on viscoelastic scattering problems inlinear acoustic medium by means of hp boundary and finite elementapproximations. A particular emphasis is placed on an a-posteriori errorestimation for the viscoelastic scattering problems
