| Abstract: | Thin walled tubular specimens of 0 44%C, 0 28%Si, 0 66%Mn steel were used for the tension torsion fatigue tests All tests were total strain controlled under complex tension torsion cyclic loading. In the case of complete reverse as well as existing mean strains of tension or torsion, the varying behaviors of the stress response values for tension and torsion were measured for both proportional and nonproportional loading conditions. The results show that the hardening/softening characteristic of the stress response depends on the stain path and loading parameters. In addition, multiaxial fatigue life is also affected by the mean strain to some extent. |
