Using the five--dimensional stress space proposed recently by Lequeu et al., theyield subsurface on any two of the three shear stresses can be considered approximately as in-scribed circles of their corresponding subsurface on π plane. Based on this concept, the HHHyield function has been transformed into the form where the parameters are uniquely deter-mined by two crystallographic factors: the mean Taylor factor in plane strain (M_p) and thecritical shear stress (τ_c) on slip systems. Key words： polycrystalline plasticity    yield function    cubic metals 收稿日期: 1992-04-18      基金资助:国家自然科学基金 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 陈积伟 连建设 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1992/V28/I4/5 1 Taylor G I.
