Prediction rolling force in hot rolling AISI316 stainless steel plate using a large-deformation constitutive model
A large deformation constitutive model of AISI316 steel was established based on the experimental data of hot torsion.According to the established constitutive model,the hot rolling process of AISI316 steel was simulated and calculated by the three-dimensional finite element method,analyzed the calculated rolling force and the measured rolling force.The results show that the calculated value is about 7%lower than the measured value at the reduction rate of 30%-50%.When the reduction rate is 65%,the calculated value is about 12%lower than the measured value.In the range of industrial applications,the rolling force calculated by the determined AISI316 steel large strain constitutive model has high prediction accuracy.
