Good Agreement

The internal state variable method may be the best tool，offering researcher the model framework，certainly based on physical mechanism. A constitutive equation model framework，reported in this study， has been proposed to predict the distribution of stress of EA4T steel. The constants ，arising in this model ，are determined using an evolutionary programming (EP) optimization technique . A good agreement between the computational and experimental results was found.
