Photoelastic Analysis of Stresses in Composites

  • Vincent J. Parks
Conference paper


The term “composite” in this paper will be used in a somewhat broader sense than in the usual definition. Consider a series of materials and structures; first, a typical composite material, random fibers of glass embedded in a plastic matrix; second, fibers oriented in one direction in the plastic matrix; third, the fibers oriented in varied directions, layer by layer, in the plastic. Fourth, consider single layers of unidirectional fibers in plastic that are cast and subsequently bonded to each other with the fibers in varied directions, to give a system very similar to the one previously described. Fifth, consider fiber reinforced layers bonded alternately to layers of a homogeneous material such as a metal, ceramic or glass. Sixth, consider layers of two different homogeneous materials bonded together. Finally, consider two irregular shapes of different materials bonded together. All the above examples are here termed composites.
