| Abstract: | This paper deals with the interaction between subinterface cracks in biamaterial orthotropic materials. The original multiple cracks problem is decomposed into the subproblems containing only one crack. Introducing the complex potentials modeling dislocation singularity near the interface, a system of singular integral equations are derived from the traction free conditions on the crack faces. After determining the dislocation density functions, the stress intensity factors at the crack tips are given. |

| Keywords: | crack interface stress intensity factor dislocation |
