摘要
引入变量分离的位移函数,用里兹法(Ritz)求得了矩形薄板在对边简支另对边自由受均布载荷作用时的挠度近似函数。和精确解相比。本近似解具有计算简捷和良好精度的特点。
This paper discusses by Ritz method the proplems of the bending of rectangular plates with two opposed edges simply supported and the other two opposed edges free under uniformly distributed loads. The calculation is simple and the accuracy is satisfactory.
