摘要
The dynamic anti-plane response of a bi-material half space including a circular hole and periodic interfacial cracks is investigated. An analytical model is established for periodic type III cracks that adopt the idea of "conjunction" modeling. The definite integral equations suitable for modeling the existence of multiple interfacial cracks are derived that satisfy the continuity conditions at the interface. Numerical calculations are carried out to find the dynamic stress concentration factor (DSCF), whose results indicate that the number of interfacial cracks has a significant effect on the dynamic stress concentration around the hole edge, especially for low-frequency incident SH waves.
