Abstract
Since experimental techniques using dynamic photoelasticity are in general limited by suitably intense monochromatic light sources, it was of primary importance to describe a ruby laser system which would completely remove this particular aspect of the problem. Modulation of the system, in this case by a Kerr cell, provides the necessary control of the light output such that a complete series of results can be obtained by putting together the results of many individual tests recorded on a conventional still camera. In this case the dynamic stress concentration factor in a strut with a symmetrically located circular discontinuity was determined to definitely establish the potential of the system.
