Fig. 975 View of the fracture surface in Fig. 974 . The rivet hole intersected by the fracture is abnormal, consisting of two overlapping holes (see Fig. 976 ). Beach marks, which are clearly visible, indicate that the fatigue crack began at the double-drilled rivet hole. 1.13× More

Fig. 976 Higher-magnification view of the rivet-hole area of the fracture surface shown in Fig. 975 . The double-drilled nature of the rivet hole is shown quite clearly here. Two fatigue cracks originated at this hole—one beginning at arrow A and growing to the left, and the other beginning More

Fig. 769 Surface of a low-cycle fatigue fracture in the collar of a rivet-heading tool of AISI S1 tool steel heat treated to a hardness of 56 to 58 HRC. Following the development of the smooth fatigue zone at right, fracture occurred in a few hours of service, generating the unusual beach More

Fig. 18 Schematic of buckling failure of a thin sheet in a riveted joint. Countersinking the top sheet formed a sharp edge at the faying surface. More
