Resumo
The Boundary Element Method (BEM) has been distinguished by its good performance in several applications where the field of variables is stationary and the constitutive medium is homogeneous. However, there are a range of problems in applied physics and engineering that are known to be difficult to solve by BEM. Among these are the physically inhomogeneous problems, where physical properties may vary locally or sectorally. For these problems, domain formulations such as Finite Element Methods (FEM), Finite Volumes (FVM) or even Finite Differences (FDM) have considerable advantages. However, even for these cases, it is possible to obtain consistent formulations for the BEM, such as the sub-region technique. In this work, an alternative technique is presented, within the scope of the BEM, to solve sectorial homogeneous elastic problems. This new formulation has already been successfully tested on Laplace's Problems. The goal is extend it to stationary cases of elasticity and to evaluate its applicability in this new class of problems.
