In the theory of thin plates, the bending of cantilever rectangular plates has long remained one of the most difficult problems in this field of study As a consequence, the solution now available are all limited to the approximate ones.

In this paper it is attempted to get an exact solution, which satisfies both the differential equation and the complicated boundary conditions including the free corners.

在薄板理论中,悬臂矩形板的弯曲,长期以来是个难题,因而,现有的解均属于近似解,如列出几位曾解过这问题的作者,可提到L.V.Kantorovich,D.L.Holl,W.A.Nash,H.J.Plass,Jr.等.他们所用的方法为变分法或差分法.本文将作出一个精确解.它满足微分方程及复杂的边界条件,包括自由角点条件.在我们的方法中,用了叠加法及广义简支边这概念.它的特点是:沿边各点的弯矩为零,但挠度是存在的,因而要满足自由边的条件.只须消除剩余的剪力.顾及自由角点的位移,只须叠加符合要求的一些简单的弯曲面方程.所得的结果与近似解很好地核对,充分证实了现在这解是正确的.

In this paper, a new mixed variational principle of energy in linear elasticity the state-parted variational principle of energy is presented.If an elastic body with complex surface S is in static equilibrium, Let the part Su1 transform into Sσ1 and the part Sσ1 into Su1. The body having the surface is called the BASIC SYSTEM of the original body.Let us divide the state of the basic system into two sub-states called sub-states (1) and (2).Let us consider the sub-state (1) having potential energy and the sub-state (2) having complementary energy and define the energy H. The functional of the state-parted variational principle of energy are as following: + H and so on.Problems dealing with a body having complex boundary conditions can be solved by means of the state-parted variational principle of energy.

本文提出了线弹性体力学的一类混合能量变分原理——分态能量变分原理。 文中首先定义了对弹性体施行边界变换以后获得的基本体系状态,然后把基本体系状态分解成两个子状态。对这两个子状态分别建立位能泛函和余能泛函,并定义两子状态之间的附加能量。从而可以构造出一族分态混合能量泛函。除了详细地论证了三种典型的分态能量变分原理以外,文中还列出了分态能量泛函的其它一些形式。 最后,说明了分态能量变分原理在计算具有复杂边界条件薄板问题中的应用。
