INTERACTION MBETWEEN INTERFACE MACROCRACK AND MICROCRACKS

With the use of the dislocation method of complex potential function, this paper studies the interaction between the interface macrocrack and the interface or beneath-interface microcracks by the construction and numerical solution of singular integral equations. The results show that the remote field phase angle ψ and Dunder′s parameter α have great influnce on the interaction between interface macrocrack and microcracks, while the effect of ψ on the shielding zone is far less than that of α.
