摘要
本文研究了悬臂矩形板受均布载荷或集中载荷作用时的侧屈问题.挠度函数选用多项式(2.1)以取代文献[1]中的余弦函数.本文得到的最小临界载荷比文献[1]相应结果更加准确,计算过程也十分简单.
The present article researches the problems of the lateral instability of cantilever rectangular plates under a concentrated force or a uniformly distributed load respectively. We select the polynomial (2.1) instead of the cosecant function in ref.[l] as the flexural functions. The minimum critical load obtained here is more exact than the results obtained in ref.[l].
