虚拟层合单元在有限元结构分析中的应用

利用等效数值积分化“分”为“合” ,把原来需要多个单元才能进行分析的多层、不同材料归为 1个单元内部的层 ,从而使有限元分析的单元数目大大减少 ,计算效率大为提高。

“Fragments” are turned into an “entirety” by using the equivalent numerical integration, i.e. the multi-layers and different materials, which could only be analyzed by making use of many units in the past, are incorporated into an internal layer of a unit, so that numbers of the units for finite element analysis can be greatly reduced, and calculation efficiency can be improved considerably.
