摘要
利用冯.卡门广义大挠度理论,建立了具有初始缺陷任意铺层的板的非线性稳定性控制微分方程。运用Galerk in法对其进行处理,得出非线性方程组。通过采用载荷增量和Newton迭代相结合的方法对非线性方程组进行求解,追踪出后屈曲平衡路径。通过实例并与当前结果进行比较,显示相当好的一致性。
Based on Von-Karman＇s large deflection theory, the nonlinear stability-governing equations of composite laminated plates with imperfections are established. The nonlinear equations are obtained with the Galerkin＇s Technique. By using load increment and Newton iteration method in combination, the nonlinear equations are solved and the postbuckling equilibrium path is determined. The validity and effectiveness of the method are demonstrated by comparing the solutions obtained by other existing methods.
