A dynamic photoelastic investigation of stress-wave propagation in cones - Paper discusses further developments of the embedded-polariscope method for dynamic three-dimensional applications

Abstract

The embedded-polariscope method was employed to isolate the central plane in cylindrical and conical models subjected to axial loads. Light-field isochromatic-fringe patterns associated with each of the five models studied were recorded by using a multiple-gap camera. Results obtained indicate that the maximum stress decays with distance propagated approximately as indicated by the elementary one-dimensional wave theory. © 1968 Society for Experimental Mechanics, Inc.
