%X An approximate method of interaction of multiple cracks is extended to the study on interaction of frictional cracks in rock-like materials. The cases of two inclined collinear cracks and a pair of offset parallel cracks are discussed in detail. The results obtained show that interaction between cracks could produce either an enhancement or a shielding effect on the stress intensity factors depending on the positions of the cracks. The method can be used to study further the mechanism of propagation and coalescence of cracks in rock-like materials.
