Abstract
A photoelastic technique has been developed to determine accurately the fringe order of a sharp notch, i.e., as small as 0.0019 in. in radius, to within ±0.0004 in. of the boundary. The stress is frozen into the specimen, enabling careful study of the specimen. Experimental results are discussed and compared to values obtained from some existing theoretical solutions.
