Title:Low cycle fatigue in torsion
Author(s):Halford, G.R.; Morrow, JoDean
Abstract:Completely reversed torsional fatigue failures are reported for two aluminum alloys, 60-40 brass and SAE 4340 steel, in the life range of ½ to 20,000 cycles. Cyclic hysteresis loops were measured and the total plastic strain energy to cause fracture is reported. The results are interpreted using hysteresis energy as a criterion for fatigue damage and also in terms of the Coffin Equation for low cycle fatigue. Both methods of interpretation give good agreement with tests results. For practical purposes, the data is adequately described by substituting shear strains for normal strains in the Coffin Equation.
