【Abstract】 In this paper,the J integral analysis is performed for the plane problems of multiple microcracks near the tip of a semi infinite macrocrack in an anisotropic elastic solid.The relation between the contribution induced from the microcracks and that induced from the main crack is shown in a consistent way.更多还原
