The tendency of variation of three orthogonal size of workpiece is illustrated in Fig. l. It is assumed that. unrolling the Mises circular cylinder to a plane is a convenient method, and σ_m-θ stress plane is given first(σ_m-mean stress,θ—characterized strain angle). And the equations of interface between various regions are also given. Finally, the location of typical metal forming processes in stress plane has been illustrated in Fig.5 from which the tendency of variation of three orthogonal size may be judged and the resistance and plasticity of metal forming processes may also be compared. 收稿日期: 1982-04-18      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 王仲仁 李守栋 刘立君 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I4/433 1 刘淑仪,锻压技术,(1979) ,№.5,4． 2 Johnson, W.; Mellor, P.B., Engineering Plasticity, Van Nostrand Reinhold, London, 1973, p. 68． 3 王仲仁,哈尔滨工业大学科学研究报告,1979,№.49． 4 王仲仁,锻压技术,(1979) ,№5,19． 5 王仲仁;李守栋,哈尔滨工业大学科学研究报告,1979,№.55． 6 斯德洛日夫,M.B.;波波夫,E.A.,金属压力加工原理,哈尔滨工业大学锻压教研室;吉林大学锻压教研室译,机械工业出版社,1980． p.121． No related articles found!
