| 摘 要： | 基于立方对称结构的晶体特点，本文建立一种唯象连续非线性本构模型，推导出一些主要方向如（００１）、（０１１）和（１１１）受单向载荷时的表达式。并对所建模型的适用性进行了分析，指出在较高温度状态时所建模型能较准确地描述Ｎｉ基单晶的非线性变形。

| Abstract: | Based on the cubic symmetry,a cubic continuum mechanical nonlinear constitution is built for theNickel--base single crystal superalloys. The strain rate expressions on the single loading on some main crystallographic orientation is obtained,and the applicability of the constitution is analyzed. It is found that the built modelhas high applicability at high temperature,and can be applied to describe the nonlinear deformation of Nickel-basesingle crystal superalloys. |
