Determination of Stress Intensity Factors from Photoelastic Data with Applications to Surface Flaw Problems,

Abstract

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)
