Application of the Multiple-Spark-Gap Camera to Dynamic Photoelasticity

J. W. Dally, L. V. Brillhart

A multiple-spark-gap camera, for use in dynamic photoelasticity, closely meets the requirements of the optimum system. The camera operates at framing rates between 50,000 and 500,000 frames/s. It is capable of resolving a dynamic pattern with a fringe gradient of 20 fringes/in., traveling at a velocity of 75,000 in./s. Other design details are given and typical results are illustrated by considering the propagation of several types of stress waves in a half-plane dynamically loaded by a point charge on the boundary.
