PHOTOELASTIC STUDY OF WAVE PROPAGATION AROUND EMBEDDED STRUCTURAL ELEMENTS

Photoelastic methods have been used extensively it recent years to determine stress distributions associated with a propagating stress wave. In this paper a series of studies are described which have been conducted to determine stresses in the free field of a two-dimensional plate and of the boundaries of embedded structural elements in the plate during passage of a stress wave. Both explosives and traveling air shocks were used to generate the stress waves. Results for circular holes and rigid circular inclusions are presented and compared with equivalent static stresses based on the free field conditions. Important conclusions are drawn regarding dynamic stress concentration factors. /Author/
