Abstract:
      In this paper a virtual boundary element-collocation method is presented for solving problems of elasticity, which can improve obviously the calculating accuracy of displacements and stresses near the region of boundary than the classical boundary element method and any other numerical method.Some examples show that the accuracy in the internal domain including the subdomain near the real boundary is quite higher than one of any other numerical methods. There is no any singular integral in this method. The results of examples are quite satisfactory.
