Two series of dynamic photoelastic experiments utilizing line charges of lead azide are described. In the first series of tests, the stress waves generated in a full-plane model by three different ignition methods are investigated. The second series of experiments is performed on photoelastic models of a quarter-plane where the distance between the line charge and the parallel free surface is varied for these tests, double-end ignition is employed. The reinforcement of the incident shear wave by reflected stress waves is studied and the effects of varying the spacing between the line charge and the free boundary are indicated.
