Abstract
Generally, the boundary element method (BEM) for thin elastic plate bending analysis uses two different types of integral equations for displacement and rotation. However, there is a different type of approach, based on a direct method, using only integral equations for displacement (single integral equation method). In this method, hyper-singularities do not arise, because there is no need to use integral equations for rotation. In the present paper, the regularizing operation using the rigid rotation mode, as suggested in the first report, is applied to the single integral equation method. Through the numerical results of a square plate under several boundary conditions, it is shown that results obtained using this method are more accurate in comparison with the without regularization.
