...) 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...

Samples that were welded with the high heat input procedure, which promotes carbide precipitation and residual stress, cracked after 168 h of exposure, whereas samples that were welded with the low heat input procedure remained crack free. These results were considered significant because...

It is significant that the rim and flange are normally in residual compression because of their manufacture; the compressive stresses caused by thermal expansion are added to these stresses. Upon release of the brake or stopping of the train, the rim and flange cool and contract...
