抄録
In the field of bar rolling, there is little theoretical research, because the flow of material in bar rolling is complicated. Recently, we proposed a new energy method using finite element division, and this method was applied to the analysis of the flow of material in two types of bar rolling : square-diamond pass and round-oval pass. Howeve there is still an important type of bar rolling : square-oval pass. In this type, the side region of the material is reduced earlier than the other part, whereas the central region of the material is reduced earlier in the former two types. So the flow of material in this type differs a lot from that of freedom of velocity fields must be increased for precise simulation of the flow of material. In this paper, we have improves the method to lessen computation time and memory requirements. Then, this method is applied to the analysis of material flow in square-oval pass, and reasonable results are obtained for rolling properties such as width spread, strain rate distribution, folding of stress-free side surface, etc.
