摘要
利用有限元软件Patran-Marc模拟在各种边界条件和荷载作用下正交各向异性板的屈曲失稳形式，研究了不同的边界条件和受力情况对板的屈曲的影响，得到了正交各向异性板屈曲的一般规律．分析了FRP复合材料构件的局部屈曲，并与相应的正交各向异性板的屈曲进行对比，阐述了正交各向异性板的屈曲理论在构件中应用的特点．分析结果对FRP复合材料构件在轴压以及复合受力作用下的稳定性设计具有一定的参考价值．
A buckling analysis of orthotropic plate under different boundary conditions and different force types was simulated using Patran-Marc finite element software. The stability principle of orthotropic plate under axial compression was obtained by analysing a series of numerical models with different boundary conditions. A local buckling of composite materials was investigated and the local buckling load between the orthotropic plate and fiber reinforced plastic component was compared, also the application characteristic of orthotropic plate buckling theory in components of FRP composite materials was expounded. The conclusion with the local buckling provided a base for design of the local buckling under the axial load for fiber reinforced plastic plate.
