摘要
The bending of rectangular plate is divided into the generalized statically determinate bending and the generalized statically indeterminate bending based on the analysis of the completeness of calculating condition at the corner point. The former can be solved directly by the equilibrium differential equation and the boundary conditions of four edges of the plate. The latter can be solved by using the superposition principle. Making use of the recommended method, the bending of the plate with all kinds of...
在分析角点求解条件完备性的基础上将矩形板弯曲划分为广义静定问题和广义超静定问题 .广义静定弯曲可以由板的平衡微分方程及四边边界条件直接求解 ,广义超静定弯曲可以由叠加法求解 .这种求解方法可以解决各种边界条件下 (包括简支边、固定边、自由边、自由角点、支柱角点 )的矩形板在任意荷载作用下 (包括板面上作用任意法向荷载 ,板边界上作用任意荷载 ,板自由角点上作用集中力 ,板边界及支柱角点发生任意位移 )的弯曲 .本方法可以将经典的纳维叶解和李维解法有机地统一起来 ,且收敛速度快 ,计算精度高 .
