Stress analysis of two-dimensional perforated plates using boundary element alternating method

In this paper, the boundary element alternating method (BEAM) is developed to study the stress concentration of a two-dimensional (2D) perforated plate. This method involves the iterative superposition between the boundary element solution of a bounded plate without holes and the analytical solution of an infinite 2D plate with a circular hole subjected to arbitrary normal and shear loading until the required boundary conditions of the original problem are satisfied. Excellent agreements between the solutions of the present simplified procedure and the numerical methods (conventional finite element and boundary element techniques) are observed and show the advantages of the proposed method.
