摘要
本文从变分原理的概念出发,给出了一组求解非线性稳定临界载荷的变分公式.从本文的变分公式中可非常方便地得到失稳临界载荷的上限值.
In this paper, a set of variational formulas of solving nonlinear instability critical loads is established from the view point of variational principle. The paper shows that it is very convenient to solve nonlinear instability critical load by using the formulas suggested in this paper.
