Resumo

This paper presents a proposal for solving plane elastic problems. In the formulation a jump term and a strongly singular appear on domain integral associated with a residual stress. Only the boundary is discretized. The domains integrals are transformed in boundary integral using the radial integration method (RIM). Results for displament and internal stress are presented and show good agreement with literature.
