Abstract

The paper proposes a boundary element discretization for the analysis of 2-D elastic problems. The procedure is designed paying attention to the efficiency of the interpolation used to describe the mechanical quantities on the boundary and to the precision and the cost of the evaluation of boundary integrals. In particular, a non- traditional quadratic interpolation and an analytical integration are used. The features of the interpolation and the common structure of the kernels allow the use of the same discretization model for the analysis of plane stress and plate bending problems. Some applications relative to both problems are presented.
