摘要
简述了无应力状态控制法的基本理论,并且介绍了CR列式的基本原理.基于CR列式分析方法,分析了传统增量法和无应力状态控制法参考标架的不同,并在此基础上推导了无应力状态控制法的基本方程,得到的公式表明:采用CR列式分析方法来剖析无应力状态控制法的基本方程,是完全可行的,并且力学概念清晰.最后以实例分析了无应力状态控制法的运用.
The basic theory of unstressed state control method was addressed through introduc- tion of the principle of co-rotational formulation. Based on the co-rotational formulation analy- sis, the differences of the reference frame between the traditional incremental method and the unstressed state control method were discussed, and the basic equations of the unstressed state control method were derived. The resulting formulas show that the co-rotational formulation procedure is appropriate for analysis of the basic equations of the unstressed state control meth- od, and the derivation process has a clear mechanics concept. Moreover, the case analysis demonstrates validity and advantage of the co-rotational formulation in application of the un- stressed state control method.
