Further Applications of P-Adaptive Boundary Elements

Abstract

In previous BEM Conferences , the concepts, developments and organisation of the p-adaptive philosophy have been presented by the authors, as well as some interesting features of the hierarchisation of the solution, accuracy estimates and numerical computations optimization. This current paper is devoted to presenting some new developments and aplications in linear elastostatics, with emphasis on: a ) Efficient computation of influence coefficients, b) Efficient evaluation of the residuals by taking advantage of the hierarchy of the interpolation functions and e) New results regarding estimators and convergence ratios.In addition, several practical examples will be shown and discussed in order to point out the advantages of the method .
