Abstract
Experimental stress analysis techniques and their application to composite materials are described and discussed. These include strain gages, photoelastic coatings, moire and holography applied to glass- epoxy, boron- epoxy and graphite- epoxy composites. Strain gages are used extensively to determine stress- strain behavior to failure, strain distributions and concentrations. The technique has been extended to the measurement of subsurface strains by means of embedded gages in boron- epoxy composites. Photoelastic coatings are used to determine full- field strain distributions.
