...Abstract Abstract A 4340 steel shaft, the driving member of a large rotor subject to cyclic loading and frequent overloads, broke after three weeks of operation. The driving shaft contained a shear groove at which the shaft should break if a sudden high overload occurred, thus preventing damage...

... was to determine whether the hose failed during or before the accident. Fracture in the failed clamp was accompanied by obvious permanent deformation and evidence of local shearing at the ends of the perforation where fracture occurred, and in the adjacent perforation. The first test involved tightening the clamps...

... the pin failures. However, the extent of shear band formation is related to the observed failures. All of the failed pins had rather large, featureless segments on the band (at least 10% of the circumference); whereas the pins uniaxially tested for comparison generally did not. Without extensive...
