Abstract
The optical method of caustics was used to determine stress-intensity factors for straight cracks in compact-tension-shear (CTS) specimens. The stress-intensity coefficients measured as functions of crack lengt h and loading angle (mode I-mode II mixity) were in agreement with the results of a finite-element analysis. The CTS specimen will be used t o establish K-I-K-II fracture toughness envelope for transformation-to ughened zirconia ceramics.
