摘要
研究发现,一定尺寸的圆柱壳有一个最大临界值.这个值由圆柱壳厚度与半径比值所确定.本文给出最大值曲线,用它可以判断传统方法所得结果是否正确;估算已知尺寸下的最大临界值;确定已知临界力所需壳板厚度及决定有效的加强方法.
There is a maximum critical value in the cylindrical shell of certain dimension.This value depends on the ratio of thickness to radius of the cylinder.The maximum value curve is presented here.Using the curve,we can determine whether the result by ordinary methods is correct or not, estimate the maximum load, determine the necessary thickness and decide the reinforcement of structure.
