The weak singular integral equation of curved crack intersecting with anti-plane circular inclusions interface is established. The singular stress integral of curved crack at the intersection of anti-plane circular inclusions and interface is studied by the principal analysis method of Cauchy type singular integral equation. And the stress intensity factor at the intersection is defined according to the singular stress.The stress intensity factor at the crack tip and the intersection can be obtained by numerical solution of the singular integral equation.
