- Abstract
A series of low cycle fatigue tests under stress control were conducted for notched specimen of 022Cr17Ni12Mo2 stainless steel. The tensile test results show that the yield strength and tensile strength of the notched specimen are more than those of smooth specimen. The necking phenomena indicate that the material has excellent plasticity. The fatigue lives of notched specimens were predicted by the local stress-strain approach. The predictions of fatigue notched factor form tests are more accurate than those of Peterson approach. The predictions of crack initiation life are in a factor-2 scatter band.
