摘要
基于Karm an 型大挠度方程,用修正迭代法分析了均布压力下夹支正交异性圆锥扁壳的几何非线性的后屈曲行为,给出二阶近似的荷载挠度特征关系式及临界荷载,给出了三种正交异性参数对应的数值结果,分析了正交异性参数对壳体变形和屈曲荷载的影响。
Based on Karman nonlinear equations, post buckling behavior of the clamped orthotropic shallow conical shell under uniformly distributed pressure is studied. By means of the modified iteration method, the approximate formulas of the second degree for load deflection and critical load are obtained, and using these formulas the numerical results as l 2 =0.6,1.4and 1.8 are calculated.
