【Abstract】 The deformation process of heavy rail at 800-I pass has been simulated using nonlinear finite-element software MARC/AutoForge by three dimensional thermo-mechanical coupled elastoplastic finite element method (FEM), and the equivalent stress and strain field, temperature field and rolling force of rolling billet were analyzed. The maximum deformation of rolling billet was at the location of waist-leg arc and leg ends of both sides of billet, and the temperature went up maximum at middle of billet near surface.更多还原
