... covered with beach marks, indicating fatigue cracking. The beach marks emanated from a 6.4 mm (1/4 in.) wide band of unusual appearance running across the center of the fracture. Saw cuts were made perpendicular to both of the fracture surfaces and across the unusual-looking bands. The cut surfaces were...

...Abstract Abstract An intermediate shaft (3 in. diam), part of a camshaft drive on a large diesel engine, broke after two weeks of service. Failure occurred at the end of the taper portion adjacent to the screwed thread. The irregular saw-tooth form of fracture was characteristic of failure from...

... approximately 8 in. long ( Fig. 1 ). Both ends of each tube had been cut with a saw. Each tube section had a circumferential weld adjacent to the saw cut on one end; this end was reportedly the inboard end. The other end of each tube was reportedly cut at the weld to the header. There was a small remnant...
