    Abstract

    The paper examines the stress state of a body with the discretized boundary embedded in the infinite domain subjected to layered or double-layered actions, such as forces and displacement discontinuities on the boundary, and to internal actions, such as body forces and thermic variations, in the ambit of the Symmetric Galerkin Boundary Element Method (SGBEM). The stress distributions due to internal actions (body forces and thermic variations) were computed by transforming the volume intergals into boundary ones.The aim of the paper is to show the tension state in as a response to all the actions acting in when this analysis concerns the crossing of the discretized boundary, thus showing the possible presence of singularities. In the end, the displacement method by SGBEM is mentioned and some examples are presented using the KARNAK program codified by some of the present authors.
