摘要 经过 4 0年的研究开发 ,壳体有限元由低阶到高阶 ,从单变量到多变量 ,取得了很大的发展。从平板壳元、退化壳元和多变量壳元的角度进行了总结 ,对薄壳有限元发展过程中遇到的剪切闭锁、膜闭锁、伪零能模式等困难及其相应的缓解或稳定措施做了评述。 Developed from single-variable to multi-variable and from lower order to higher order,shell finite elements have been made great progress.Attempt was done to review the advances of thin shell finite elements in the form of faceted shells,degenerated shells and multi-variable shells.Difficulties appeared during the development of thin shell finite elements such as shear locking,membrane locking and spurious zero energy modes were elaborated,corresponding alleviating methods or stabilization measures were also presented.Finally,potential developments for thin shell finite elements were discussed
