Improved computational methods have been developed to determine, from photoelastic fracture patterns, those stress field parameters additional to the stress intensity factor, that are associated with different fracture test specimen geometries. The variations with crack tip position of these non-singular terms in Modified-Compact-Tension and Rectangular-Double-Cantilever-Beam specimens have been studied. Results have been utilized to formulate criteria that can be used to quantify the concept of the singularity-dominated zone around a crack tip in specimens of finite dimensions.
