| Abstract: | Antiplane multiple curved crack problem in circular inclusion and matrix material is considered. In order to solve the proposed problem, two kinds of elementary solutions corresponding to a point screw dislocation in inclusion and matrix material respectively are presented. Utilizing the elementary solutions and taking the density of dislocation along cracks surfaces as unknown functions, by the principle of superposition, a group of weakly singular integral equations with log kernels can be obtained. After the numerical solution of the integral equations, the discrete values of dislocation density are obtainable. So stress intensity factors at the cracks tips can be calculated, and several numerical examples are given. |
