Abstract
An investigation is made of the convergence of boundary element approximations of variational solutions of the boundary-value problems of linear elasticity theory, using double- and simple-layer potentials (DLP, SLP) /1, 2/. Auxiliary propositions are proved, concerning the basis property of the approximating sequence of potentials. The results may also be used to justify variational formulations of the boundary element method (BEM) is applied to the solution of other second-order elliptic boundary-value problems.
