| Abstract: | In the usual formulation of singular equation approach for crack problems in plane elasticity [1,2], if one changes the right-hand term of the integral equation from tractions to resultant forces, a new integral equation can be obtained and is presented in this paper. The newly obtained integral equation has a log singular kernel. Interpolation equation for the dislocation functions (the undetermined functions in the integral equations) is proposed. Numerical examination is used to demonstrate the efficiency of the present technique, and a number of numerical examples are given. |
