摘要: 利用普适开折理论研究了多重缺陷对工程结构临界载荷的影响.对音叉问题给出了由缺陷引起的结构临界载荷改变量的下界估计公式及相应的简单、有效的数值计算方法.Abstract: By means of the theory of universal unfolding, the influence of multi-imperfections upon the critical load of structure in engineering is analysed in this paper. For the pitchfork problem, a lower bound of increments of the critical loads caused by imperfections of the structures is given. A simple and available numerical method for computing the lower bound is described.
