| Abstract: | Thermo-mechanical coupled elasto-plastic FEM model of universal rolling has been built for Laigang's large size H-beam by FEM program LS-DYNA.Using the FEM model,simulations of different friction coefficients have been carried out.By analyzing the simulation results,the influence of contact friction conditions on the metal flow and rolling force is gained. |
