Variational Principles of Asymmetric Elasticity Theory of Finite Deformation

Mechanics Department, China University of Mining and Technology, Beijing Campus, Beijing 100083, P R China

摘要: 应用有限变形S-R分解定理,将体力矩重新定义为内外两种体力矩之和,给出了相应的变形能增率表达式及其物理意义,并进一步补充和完善了有体力矩作用下的有限变形力学的功率变分原理和余功率变分原理。

Abstract: In this paper, based on the finite deformation S-R decomposition theorem, the definition of the body moment is renewed as the sum of its internal and external. The expression of the increment rate of the deformation energy is derived and the physical meaning is clarified. The power variational principle and the complementary power variational principle for finite deformation mechanics are supplemented and perfected.
