摘要：

A new approach to the solution of stress intensity factors from isochromatic data has been developed and is based on complex Fourier analysis. Solutions are shown to be accurate when the loading of the crack tip is predominantly Mode II and also for cases that are generally mixed-mode. The new method and its application to a four-point-bend test is described in this paper. Tests on angled-edge-cracked specimens have also been performed to show the validity of the method for a range of mixed-mode loadings.
