大变形非线性弹性理论中的新的能量原理

New Energy Principle in Nonlinear Elasticity With Finite Deformations

本文用新的推导方法,建立并证明了大变形非线性弹性理论中新的能量原理(广义变分原理),这可作为构造新的有限元模型的基础定理.

In this paper new energy principle, in nonlinear elasticity with finite deformation is established and proved by a new method. Or may be used as basic theorem for constructing some new finite element models.
