Abstract：The design of a mode of the spatially truncated rigid cone element to con-form with the metal flow was made by the application of the upper bound the-ory-upper bound element technique.The problem to estimate the upper bound ofaxisymmetric extrusion deformation force may be solved consequently.Solutioncalculated by this mode after trial done on practice is in agreement with the actu-al one and the precision of calculation of the extrusion force seems to be muchimproved. 收稿日期: 1985-02-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 许其亮 史文华 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I2/102 1 Slater,R.A.C.,Engineering Plasticity Theory and Application to Metal Forming Proceses,Macmillan Press Ltd,London,1977,p.394,398． 2 木内学;村田良美,塑性(?)加工,22(1981) ,495． 3 #12 4 Johnson,W.;Kudo,H.,The Mechanics of Metal Extrusion,Manchester University Press,1962,p.60,102． 5 徐秉业;陈森灿,塑性理论简明教程,清华大学出版社,1981,p.283,304． 6 西山卯二郎,塑性加工学,养贤堂发行,1977,p.268． 7 汪大年,金属塑性成形原理,机械工业出版社,1982,p.235． 8 杨守山,有色金属塑性加工学,冶金工业出版社,1982,p.240． 9 重有色金属材料加工手册编写组,重有色金属材料加工手册,(第四分册),冶金工业出版社,1980,p.19． 10 许其亮,未发表资料,1983． No related articles found!
