摘要
本文从三维空间的弹性理论中三类变量的广义变分原理推导出薄板弯曲问题的经典理论,从而证明了弹性力学精确理论与近似的薄板弯曲问题经典理论在能量原理上的统—.
This paper deduces the classical theory of thin plate bending from the generalized variational principles of the tree type variables which belongs to the tridimensional theory of elasticity, thusproving the agreement on energy principles between the accurate theory of elasticity and the proximal classical of thin plate bending.
