摘要
本文用有限元法分析了复合材料层板为面板的夹层壳的非线性稳定性问题,求得屈曲时的临界载荷因子及初始后屈曲参数.通过对飞机雷达罩的稳定性计算,表明本文分析与试验结果是吻合的.
The paper uses FEM to analyze the nonlinear stability of composite Laminates with sandwich and gives out the factors of critical load and initially post-buckling parameters. From the analysis of the stability of radar cover, we can see that the results of the paper are almost the same with that of the test.
