Abstract : An approximately square epoxy slab (approx. 14 in x approx. 14 in x 1 in) with four different edge geometries was bonded to a rigid plate on one of its faces. In the process of 'freezing' photoelastic effects a state of restrained shrinkage developed. Slices removed from the slab were used to determine the concentration factors corresponding to the four geometries. (Author)
