Modeling Uniaxial Saturated Ratcheting Strain for 1Cr18Ni9Ti Stainless Steel

A set of uniaxial ratcheting tests for 1Cr18Ni9Ti stainless steel were carried out at room and elevated temperatures. The effects of peak stress, mean stress, low cyclic stressing histories and temperature on saturated ratcheting (SR) strain were investigated. Based on the parabolic relation between peak stress and SR strain, and the linear relation between ratcheting stress and temperature, the saturated ratcheting evolution models at room and elevated temperatures were presented by using single-specimen method.
