摘要
以控制变分的概念探讨有限变形非对称弹性力学中两类变分原理的泛函π_1和π_2,并在此基础上用换元乘子法提出能满足全场方程的控制变量广义变分原理。
Two kinds of functional of variational principle π_1 and π_2 are studied in the concept of controled variational, and consequently the controled generalized variational principles are proposed using exchanging element method.
