Abstract
A recently developed semi-analytical method, called scaled boundary finite element method, is applied to evaluate the coefficients of stress field at a crack-tip for two-dimensional linear-elastic cracked structures. The method has ability to analytically compute stress and displacement field of singularities region at the crack tip more accurately without any a priori assumptions. A simple and independent formulations for evaluating the coefficients, not only of the inverse square root singular term but also of the constant and higher order non-singular terms, of the stress fields near crack-tip is presented by comparing the stress along the radial points ahead of the crack-tip with that of standard Williams' eigenfunction solution for the crack-tip. The accuracy and efficiency of the formulations are examined by numerical examples for a range of crack sizes. The results are in agreement with available solutions in literatures
