摘要
本文以Donnell型扁壳理论为基础,采用位移型理论,用Galerkin法分析了在均布外压作用下玻璃/环氧复合材料截顶圆锥壳体的稳定性问题,得到了临界外压的近似解析表达式。数值结果表明,临界外压的理论预示值与已知的理论结果和实验结果非常吻合。本文所得结果可供工程设计应用参考。
Based on the theory of Donnell oblate shell and the theory of displacement, the stability of truncated cone shell made of GF/EP composite is analysed by adopting Galerkin method with homogeneous-distributed external pres-sure.The result indicates that the theoretical prodication dates of critical pressure are well coupled with both known theoretical rcsults and experimental results.
