本文简明地回顾了安定性理论的发展过程,阐述了虚拟弹性反应的真实物理意义,在引入初值条件空间和动力荷载空间的概念后,重新表述了连续体的两个动力安定定理。
This paper briefly reviews the development process of the stability theory and describes the real physical meaning of the virtual elastic response. After introducing the concept of the initial condition space and the dynamic load space, the two dynamic stability theorems of the continuum are re-presented.
