“…Among the experimental methods the method of photoelastlcity is the most developed. There has been numerous photoelastic studies of SIF for single cracks [4][5][6][7], multiple interactive cracks in isotropic materials [8] and single cracks in orthotropic materials [9]. However, there has not been any photoelastic studies of SIF in sharp re-entrant corners, and most work in this area has been limited to numerical analysis.…”

“…EyeCom System [5,6,49] The image analysis system used in collecting data and regenerating the fringes is called "EyeCom III" system. This is an image processing machine which combines three types of man-machine communications, alphanumeric, graphic, and pictorial into a single entity to provide the tools necessary for efficient image processing.…”

“…Theory of Photoelasticity [44,6,45] When certain polymeric transparent materials are subjected to stress, they become temporarily birefringent (double refractive As the light travels through the thickness, one of the components is progressively retarded relative to the other, and a phase shift (relative retardation) occurs between the two light components. This phase shift is proportional to the principal stress difference and the model thickness at each point.…”

Mahinfalah, Mohammad, "Photoelastic determination of stress intensity factors for sharp re-entrant corners in plates under extension " (1988 INFORMATION TO USERSThe most advanced technology has been used to photo graph and reproduce this manuscript from the microfilm master. UMI films the original text directly from the copy submitted. Thus, some dissertation copies are in typewriter face, while others may be from a computer printer.In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyrighted material had to be removed, a note will indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are re produced by sectioning the original, beginning at the up^r left-hand comer and continuing from left to right in equal sections with small overlaps. Each oversize page is available as one exposure on a standard 35 mm slide or as a IT x 23" black and white photographic print for an additional charge.
