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
