Abstract:  
Analytical studies of fatigue fractures in torsion bar springs for military vehicles that, in spite of inherent planes of weakness, show that torsional fatigue failures are caused by and develop normal to the tensile component of the applied stress. Data bearing on the characteristics of torsional failures obtained from fatigue tests of torsion bars that were subjected to experimental variations in processing.
