Abstract
Fully reversed constant strain amplitude PC and CP tests were conducted on 316LC austenitic stainless steel thin-walled tubular specimens at 1023K in air under proportional push-pull and cyclic torsion loadings. The experimental data were analyzed based on the strainrange partitioning concept, and the partitioned equivalent inelastic strain range Δε_<ij> versus life N_<ij> relations (ij=pc,cc) were obtained, and the values of multiaxiality factor MF at the peak equivalent stress were determined for all of them. The effect of stress state on the partitioned inelastic strain range versus life relations was examined by comparing the results obtained in the present study with
