Abstract

In order to accurately describe the ratcheting behavior of material at high temperature,an experimental research was carried out on the uni-axial and non-proportionally multi-axial ratcheting of 304 stainless steel at 350℃ and 70 0℃.The ratcheting behavior under different loading paths and different load conditions was studied.It was shown from the study that the non-proportionally multi-axial ratcheting of 304 stainless steel at high temperatures has distinct dependence on the stress amplitude,mean stress,temperatures and loading paths.This result is useful to establish constitutive model for the non-proportionally multi-axial ratcheting of material at high temperature.
