| 摘 要： | 本文根据稳定性分析的前屈曲完全理论和修正型的Ｈａｈｎ－Ｔｓａｉ非线性本构关系，采用有限元法分析了复合材料层合回转壳的非线性稳定性，讨论了屈曲产壳体法向与面内支承条件和复合材料的横向和剪切非线性性能对壳体结构总体稳定性的影响，为工程结构设计者们提供了一些有益的参考意见。

| Abstract: | This paper inverstiates nonlinear stability of laminated composite conical shell by using Finite Element Method.The approach is based on prebuckling completed theory(PBCT) and modified Haha-Tsai nonlinear strees-strain relations for cotnPOisite materials.The computational results show that the effect of normal and triplane edge constraints of shells and both shear and transverse nonlinearities must by taken intoaccount in the evalution of buckling load for stability analysis of laminated composite shells. Certain conclusions from numerical results are useful for the designers and analysts for composite engineering structures. |
