3-D Photoelasticity and TV-Holography for the Analysis of Rotating Components

  • R. W. T. Preater

Abstract

Two and three dimensional photoelasticity is an extremely useful stress analysis tool for the design and development of complex engineering structures. Confirmation by analysis of the prototype may become more difficult however for economic reasons. The development of a non-contact method of analysis requiring the minimum surface preparation and plant shutdown is therfore doubly attractive. Electronic Speckle Pattern Interferometry (ESPI) or Tv-Holography using a pulsed laser is a technique which displays considerable industrial potential in this way.
