初参数法在压杆稳定性问题中的应用

The Application of Initial Parameter Method in Buckling of the Bar——Further Demonstration of the Bifurcation Point Theory

分支点理论是现代弹性稳定性领域中的重要理论之一。近几十年随着这一领域的深入研究,分支点理论的重要性及其地位遂步地被确定,本文是在应用方面为该理论提供的佑证。

The“Bifurcation point theory”is one of the modern improtant theorys about elas- tic stability.In recent decades the importance and position of“Bifurcation point theo- ry”is established step by step. The objective of this paper is to provide some further demonstration to this theory in its application.
