Abstract
Yield surface distortion and its center movement were employed in a unified viscoplastic model to predict the ratcheting behavior of the 304 stainless steel. A combination of the Ohno-Wang model and the yield surface distortion model of Baltov and Sawczuk was used in uniaxial loading. Stress amplitude and the mean stress were varied in the tests to verify the model. Uniaxial loadings were simulated with and without consideration of yield surface distortion. Results from both simulations were compared. Yield surface distortion showed a significant effect on the simulation of the ratcheting responses.
