The Fundamental Formulas of Generalized Indirect Boundary Element Methods and Its Applications

The fundamental formulas of generalized indirect BEM for the Poisson' s and linear elasticity problems are proposed initiating from the boundary integral equation. Two numerical examples show that the generalized indirect BEM not only possess all the advantages of regular BEM , but also will resolve completely singular problems and corner problems which regular BEM often have to disentangle , and that the precision of numerical calculation can be correspondingly improved .
