摘要
在柱壳的有限元计算中 ,采用 Mindlin八结点杂交壳单元和增量荷载法 ,基于选择积分、缩减积分及完全积分三种积分模式编制了分层计算各种厚板壳的有限元程序 FEAM。
Eight nodes heterosis.incremental loading which based on selected (reduced or full)integratin are adopted during FEM engineering calculation for shells.The finite elements program FEAM using the Layered approach is authorized to analyze the deformation of shells whose thickness is variable.In the end,buckling of finite elastoplastic deformation on moderately thick cylindrical shells subjected to local normal uniformly distributed loads and concentrated couples is analyzed and calculated.
