Thereto-Piezoelectric Effects on the Postbuckling of Axially-Loaded Hybrid Laminated Cylindrical Panels

  • 摘要: 基于Krmn-Donnell型非线性壳体方程,给出带压电作动器混合层合圆柱曲板在机械荷载、电荷载和热荷载作用下的后屈曲分析.假定温度场为均匀分布,电场仅有沿板厚方向的分量EZ,且假定材料性能常数与温度和电场的变化无关.将壳体屈曲的边界层理论推广到混合层合圆柱曲板受复合荷载作用的情况.相应的奇异摄动法用于确定圆柱曲板的屈曲荷载和后屈曲平衡路径.分析中同时考虑非线性前屈曲变形和初始几何缺陷的影响.数值算例给出完善和非完善,含整体覆盖或内埋压电作动器正交铺设层合圆柱曲板的后屈曲平衡路径.讨论了温度变化、控制电压、铺层方式、面内边界条件和初始几何缺陷等各种参数变化的影响.
