In this study, we investigate systematically stress intensity factors KI, KII and KIII of the kinds of three mode for a hollow cylindrical bar with three dimensionally inclined crack. Experiments were Performed on the effect of the artificial inclined crack angle φ degree. These inclined cracks in circumferential direction are put in the surface of a hollow cylindrical bar made by the epoxy resin.
Experimental methods of stress intensity factors were proposed as the suitable methods, that was a combined method of the caustic and photoelastic stress freezing method. The mixed mode of KI and KII were determined by photoelastic method of SANFORDS (classical approach) combining with the FORTRAN language of Takahashi and Nogata in the used smallest square method.
