Use of a Taylor Series Correction Method in Photoelastic Stress Intensity Determination,

Abstract

A technique is described for extracting stress intensity factors from photoelastic data which uses a Taylor Series expansion of the in-plane maximum shearing stress in conjunction with a digital computer program. By applying the method to a variety of problems including center cracked panels, compact tension specimens, part-circular surface flaws and flat bottomed surface flaws, characteristics of the method are demonstrated, and its strengths and weaknesses are delineated. It is concluded that stress freezing photoelasticity appears to be a potentially powerful tool for estimating stress intensity factors for complex three dimensional problems. (Author)
