DISTRIBUTION OF LOCAL STRESSES ACROSS THE THICKNESS OF CRACKED PLATES UNDER BENDING FIELDS

A series of three-dimensional photoelastic experiments were conducted on plates containing through cracks which were loaded in bending with sufficient extension to prevent closure on the compressive side of the plate. Cracked plate geometries were selected so as to span the transitional "thin to thick" range. Slices were made parallel to the plate surfaces in the stress frozen material so as to remove the region around the crack tips. These slices were analyzed photoelastically and functions were evaluated experimentally corresponding to stress intensity factor distributions through the plate thickness. Results were compared with the theory of G.C Sih. Agreement was excellent with theory for "thin" cracked plate geometries. For "thicker" cracked plate geometries results diverged progressively. For all cases studied, the use of a linear distribution of the stress intensity factor function through the plate thickness appeared to be satisfactory.
