Abstract: Considering the influence of temperature, equivalent strain and equivalent strain rate, the formula of thermo-mechanical couple elastic-plastic large deformation finite element constitutive equation is deduced, based on the finite deformation theory. Experimental investigations of hot rolling of strip are carried out. Comparisons between measured values and computer simulation results show comprehensive coincidence each other.
