Abstract:

A dynamic photoelastic study of stress waves generated by multiple dilatational sources in a half plane is described. The model material is CR-39 and lead azide charges are used to produce the dilatational waves. Fringe patterns are recorded by a multiple spark gap camera. Interactions between the waves before and after reflection from the free surface are studied. The effect of varying the distance between sources and their depth below the free surface is investigated in some detail.
