摘要:
众所周知, 用实验方法测压杆临界值是有一定困难的。Sou thw ell 在他的名著An Int roduction to the T heory of Elasticit y , P .429 提出了一个方法来解决这个问题。对Southw ell的方法加以进一步的分析后, 得到了一个既简便又更精确的用实验测压 杆临界力的方法。
Abstract:
It is well known that to obtain the critical load of a column experimentally is rather dif ficult .Southw ell proposed a method to solve this problem in his famous book “An Introduction to the Theory of Elast icity” P429 .Southwell′s method is discussed again and an improved method is proposed .By this method the critical load could be obtained mo re easily and accurately .
