Prediction of Cyclic Behaviors of Mild Steel at Large Plastic Strain Using Coupon Test Results

In practice, engineers can usually only obtain material properties from monotonic tensile coupon tests. The aim of this paper is to predict cyclic plasticity of mild steel from coupon test results available. First, the theory of metal plasticity is generally reviewed, and selected models are introduced, i.e., Prager’s hardening rule, the Chaboche models, and the Yoshida-Uemori model. Calibration methods of the material parameters of each model...
