摘要：

Direct and indirect approximations using sets of non‐singular, complete Trefftz functions, i.e. the complete systems of solutions, have been successfully applied to harmonic problems.1 In this paper, the procedure is applied to a more complex situation—plane elasticity problems. The examples show that the present method can avoid the difficulties relating to singular integration and has good accuracy compared with traditional boundary elements.
