Abstract
The Boundary Element Method faces difficulties to solve problems with non-homogeneous domains. This paper aims to analyze the stress distribution and concentration in piecewise homogeneous plates using the Domain Superposition Technique, a technique developed to solve problems with heterogeneous domains based on the sum of elastic energy retained in each distinct sector. Therefore, to demonstrate the robustness and adequancy of the technique to solve plane bending problems, three types of problems in seven different configurations were simulated. In the absence of analytical solutions, Finite Element Method solutions are used as reference for error evaluation.
