Types of residual stress, measurement and formation are discussed. Residual stresses were measured on two different sizes of truck axle shafts of 1 11/16-in. and 2 1/8-in. diameter. Two specimens were taken for residual stress investigation from each shaft, one toward the flange end and the other from the splined end. Metallurgical examination was made. Results of completely reversed torsional fatigue tests made on 1 11/16-in. diameter shafts are presented. Fatigue tests were made in rotating bending on full-size large-diameter shafts of two different designs. Fatigue results are summarized. Residual stresses were measured in these large shafts. Favorable surface compressive stresses were determined for these shafts water-quenched from the tempering temperature as compared with nil stresses in those aircooled. It was concluded that favorable thermal stresses were a very important consideration in improving fatigue strength.
