RESIDUAL STRESSES IN THE PLATE FILLETS OF TWENTY-EIGHT-INCH DIAMETER WROUGHT STEEL WHEELS

Past experience with the B-28 wheel has shown that this design is susceptible to plate cracking. This reports the results of a program to determine the state of residual stress in class U untreated and class B heat-treated wheels. Measurements were made according to the procedure outlined in the AISI Steel Products Manual for Wrought Steel Wheels and Forged Railway Axles. Measurements were taken at the front hub-plate fillet and the back rim-plate fillet on each wheel. While the maximum principal residual stresses developed in the class B wheels were two to four times higher than those developed in the class U wheels, analysis by Goodman diagram shows similar fatigue properties in both wheels.
