Abstract

Pure bending with a constant curvature-rate followed by creep (hold constant moment for a period of time) or relaxation (hold constant curvature for a period of time) tests were conducted to investigate the effect of prior curvature-rate at preloading stage on the subsequent creep or relaxation behavior. Thin-walled tubes of 304 stainless steel were used in this investigation. The curvature-ovalization measurement apparatus, designed by Pan et al.(1), was used for conducting the present experiments. It has been found that the curvature-rate at the preloading stage has a strong influence on the subsequent creep or relaxation deformation under pure bending.
