Abstract

Experiments were conducted in a vertical shock tube with an optically transparent single straight chain of 20-mm diameter discs made of epoxy. The dynamic time dependent fringe patterns of the stress in the contact points between the discs were registered using a Q-switched YAG laser, a transmission polariscope and CCD cameras. The main details of the experiment, the data acquisition and the computer aid processing are briefly discussed first. Thereafter the stress wave propagation and its reflection at the chain boundaries are analyzed based on the results of photo elastic experiments and their comparison with those obtained using strain gauges.
