... stresses were caused by misalignment between the electric motor and compressor and were transmitted to the shaft through the geared coupling. Flexible-disk couplings capable of transmitting the required horsepower were installed on the shafts as a corrective measure. Alignment Bending Radii 4340...

...) to 7 deg C (45 deg F) that night. The column was shop fabricated in 12 m (40 ft) long sections of 19 mm (3/4 in.) thick steel plate of ASTM A36 steel. Crack initiation was caused by high residual stress during girth welding, and the presence of notches formed by the termination of the incomplete welds...

... fabricated after field failures lasted only 50,000 cycles to failure. It was discovered that the percent coverage of shot peening prior and subsequent to the increase in failure incidence was much less than 100%, with a shot peening time of 12 min. The residual-stress state of “as fabricated” springs...

... initiated from the spring inside coil surface. Examination of the fracture surface using scanning electron microscopy showed no evidence of fatigue. Final fracture occurred in torsion. X-ray diffraction analysis revealed high inner-diameter residual stresses, indicating inadequate stress relief from spring...
