摘要
本文使用转动与应变分解的近似定理,建立了新的壳体大变形近似理论.本理论最大优点是转动张量与应变张量相匹配.作为本理论的应用,导出了一系列简化理论.
A new kind of large approximated theory of shell has beenestablished by adopting the approximate strain—rotation decompositiontheorem in continuum mechanics.The accuracy of K—L Simplication isdiscussed.It is shown that the simplication has reglected the influence ofrotation at large.The present theory leads to all important classicalresults according to various conditions and different orders of approximation.
