The computer-generated animation displays the forming process of workpiece lively. The simulative results are helpful to a better understanding of the technology of liquid extrusion.Correspondent: REN Xiangqian, lecturer, Centre for computer, Wuhan Transportation University, Wuhan430063 Key words:  liquid extrusion      numerical simulation      stable alternating direction implicit(SADI) method      upper bound element technique(UBET)      Received:  18 July 1996      Service E-mail this article Add to citation manager E-mail Alert RSS Collect articles（） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1996/V32/I7/755 1MampaeyF．IntJNumerMethodsEng,1990;30:7112王祖唐,关廷栋,肖景容,雷沛,霍文灿．金属塑性成形理论,北京:机械工业出版社,1989:3093李贺军．哈尔滨工业大学博士学位论文,1991@ [1] BI Zhongnan, QIN Hailong, LIU Pei, SHI Songyi, XIE Jinli, ZHANG Ji.
