Multiaxial Fatigue Life Prediction of 50CrVA Spring Steel under Proportional Loading

Multiaxial fatigue life of 50CrVA spring steel standard specimens and eccentric specimens under proportional loading was studied with MTS 809 tension-torsion electro-hydraulic servo tester. Both kinds of specimens were calculated by the finite element software ABAQUS and the fatigue life of specimens were predicted based on the finite element results. The results show that the additional bending moment will obviously reduce the life of specimens; only the Manson-Halford model and modified Manson-Halford model can obtain satisfactory results in many prediction models selected.
