Book Description
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).

Book Description
A technique known as the Taylor Series Correction Method (TSCM) for extracting the stress intensity factor from photoelastic data is reviewed. The need for "artificial" flaws is identified and an approach due to Savin is used to evaluate the near field effects of various practical artificial flaw shapes upon the apparent stress intensity factor. Using the Sneddon-Srivastav solution for a line crack in a finite width plate, the constriction of the singular zone is demonstrated as the crack tip approaches the free edge.

Using the Sneddon-Srivastav solution for a line crack in a finite width plate, the constriction of the singular zone is demonstrated as the crack tip approaches the free edge. Results indicate that care must be taken in applying TSCM to obtain photoelastic data at appropriate distances from the crack tip. (Author).

Book Description
A Taylor Series correction to the maximum in plane shear stress was studied as a means of extending the data zone in photoelastic determination of stress intensity factors beyond the singular region of a two degree of freedom analysis. Convergence properties were obtained by comparing with several complete two-dimensional solutions. Experiments were performed on two kinds of three-dimensional problems; plates containing surface flaws in both bending and extension. Results were analyzed by both a two degree of freedom and a Taylor Series Correction Method (TSCM). (Author Modified Abstract).
