Abstract
In this paper, the stress intensity factors of interacting kinked cracks in an elastic solid under remote compression and the overall strains of the solid are determined numerically. The kinked cracks are in general asymmetric, unequal, and arbitrarily oriented and located. Each kinked crack consists of a closed frictional main crack, and traction free kinks modeled by continuous dislocation distributions. The original problem is decomposed into straight crack problems such that the main cracks are subjected to dislocation and shear traction loadings. The model is used to investigate the dependence of the stress intensity factors and the overall strains on the crack configuration, i.e., a single fault of cracks, parallel faults, crossed faults, periodic and random crack arrays, and on the geometrical and physical parameters such as the fault angle and the lateral confinement.
