| Abstract: | Thermo-mechanical coupled elasto-plastic FEM model of universal rolling was established for large size H beam on the basis of LS DYNA software.The simulations of working conditions with different leg extension waist ratios were made,and the causes of web wave were identified.The critical value of leg extension waist ratio for the web wave in H beam universal rolling was obtained. |

| Keywords: | H beam web wave leg extension waist ratio thermo-mechanical coupling FEM |
