| 摘 要： | 本文探讨横向剪切在壳体响应中的作用。基于Ｒｅｉｓｓｎｅｒ－Ｍｉｎｄｌｉｎ横向剪切应变非零的假设，导出扁球壳完整的非线性几何方程，引入平均转角的概念。建立了扁球壳进行大挠度分析的一种新模型，该模型适用于扁薄球壳到中厚度扁球壳，其控制方程仅含４个未知量。工程算例及实验研究表明该模型具有很好的精度高。

| Abstract: | In this paper, the effect of transverse shear deformation on shell is investigated.Reissner-Mindlin hypothesis is used which accounts for moderately thick and perfect geo metrical equations are derived. Introducing the average rotation, a new nonlinear analyti cal model is established by using the principle of elastic shallow shell. It is suited for spherical shell from thin to moderately thick. Its control equations merely include four un known parameters. The engineering case and experiment research show that the model presented in this paper is reliable. |
