... fatigue cracks in a bellows convolute. One such crack was recently shown to have initiated from a weld heat-affected zone liquation microcrack. The crack, initially open to the outer surface of the rolled and seam welded cylindrical bellows section, was closed when cold forming of the convolutes placed...

... of the authors [1] had established that aluminum alloys of the type used in aircraft exhibited a “reversing shear” fracture surface ( Fig. 1 ) when exposed close to an explosion center. When we examined fracture surfaces of sections from the crash, we noted the normal shear type of separation on most of them...

Abstract The stub-shaft assembly which was part of the agitator shaft in a polyvinyl chloride reactor, fractured in service after a nut that retained a loose sleeve around the smaller-diam section of the shaft had been tightened several times to reduce leakage. The shaft was made of ASTM A105...
