A Regular Indirect Boundary Element Method for Thermal Analysis

Adaptive nite element–boundary element solution of boundary value problems

An adaptive nite element–boundary element algorithm is proposed to compute an approximate solution of a given boundary value problem. The convergence in H ( ) is controlled by a boundary element based a-posteriori error estimator from which an adaptive re nement strategy is derived. Corresponding error estimates are given based on appropriate boundary element error estimates in negative Sobolev...

Adaptive Finite Element Analysis of Large Strain Elastic Response

Abatmet-Some basic studies and developments for adaptive procedures in large strain finite element analysis are presented an evaluation of higher-order elements, two pointwise indiitors for errors in stresses, a mesh generator for remeshing on the deformed contiffuration of the body, and a general mapping scheme for transferring solution variables across models. The methods discus4 constitute t...

DUAL BOUNDARY ELEMENT ANALYSIS OF CRACKED PLATES

The dual boundary element method is formulated for the analysis of linear elastic cracked plates. The dual boundary integral equations of the method are the displacement and the traction equations. When these equations are simultaneously applied along the crack boundaries, general crack problems can be solved in a single-region formulation, with both crack boundaries discretized with discontinu...
