Abstract

In this paper new methods for adaptive discretisation of the boundary element method are presented for elastic and elastoplastic analysis. The criteria used for the refinement of the mesh are not based on residual considerations but on the local variation of the solution variable of the integral equation. The adaptive procedure is shown that converges fast and is specially developed to reveal the ability of the BIE to provide high accuracy with very economic deployment of quadratic boundary and interior elements.
