摘要: 本文以变分原理推导出具有初始缺陷因子的对称正交铺设层合板的稳定性方程。从这些方程出发,以挠度为摄动参数,采用摄动技术,研究简支矩形板的稳定的后屈曲平衡路径,给出渐近式。文中用典型算例说明对称正交铺设矩形层合板的后屈曲性态。Abstract: In this paper,general equations relating to the stability of laminated plates of symmetric cross-ply with initial imperfection factors are derived by using the variational principle.Taking the deflection as the perturbation parameter,the equilibrium path of the post-buckling path of a simply supported rectangular plate is investigated with the perturbation method.An approximation expression and a typical numerical example are presented to manifest the post-buekling behavior of the rectangular plate.
