Description

The growth of two dimensional noncircular flaws was studied by three independent methods: transfer function analysis, equivalent area approximation, and direct fracture mechanics calculation. All three methods yield results varying within a few percent of one another for the simpler elliptical and rectangular geometries. Results of transfer function and equivalent area methods agree also within a few percent of each other for the more irregularly shaped flaws. The importance of these studies to NDE predictive technology is discussed.
