摘要
本文介绍了用有限元素法分析平面力和纯弯曲情况开口薄板的稳定性。给出了三角形单元的几何刚度矩阵公式。其失稳临界应力与完整平板的结果作了比较 ,指出了开口对薄板失稳临界应力带来的影响。
In this paper,It was instroduced for the stability analysis of the holed thin plates in the plane stress and the plane bend stress by the element method.The triangle element was used in the forming element stifness matrixes.The buckling load ration of the holed plate and integrity plate was gived.It was pointed out the buckling stress of the holed thin plate is smaller than it of the no holed plate.
