The elastodynamic interaction between an explosively generated Rayleigh pulse and a buried imperfection such as a cavity or an inclusion in a half plane is investigated. Dynamic photoelasticity was employed to obtain full field information for data analysis. Measurements of the stress distribution along the free boundary of the half plane and the cavity and along the cavity/inclusion interface have been made. Results show that fractures occur for shallow as well as for deeper burial depths initiating from the cavity boundary.
