【Abstract】 By using the Muskhelishvili complex methods, the issue of interaction between bimaterial incline cracks was reduced to solve the Cauchy singular integral equations, in which the unknown functions are the dislocation density functions. The equations of the stress intensity factors (SIF) were obtained and solved numerically. And the SIF is influenced greatly by the bimaterial’s constants and the cracks’configuration.更多还原
