By using the Somigliana representation and the concept of finite-part integrals, a set of hypersingular integral equations for the interaction between two parallel planar cracks in a three-dimensional finite they subjected to arbitrary loads is derived, and then the numerical methed for solving is proposed by combining the finite-part integral methed with boundary element method.
