The coupling of Finite Element Method (FEM) with a Boundary Element Method (BEM) is a desirable result that exploits the advantages of each. This paper examines the e$cient symmetric coupling of a Symmetric Galerkin Multi-zone Curved Boundary Element Analysis method with a Finite Element Method for

It is well established that severe numerical di$culties may arise when the displacement "nite element method is used to analyse the behaviour of incompressible solids and this is particularly true for axisymmetric problems. These numerical di$culties are caused by excessive kinematic constraints and
We propose and analyze efficient preconditioners for solving systems of equations arising from the p-version for the finite element/boundary element coupling. The first preconditioner amounts to a block Jacobi method, whereas the second one is partly given by diagonal scaling. We use the generalized
