小片试验与几种非协调有限元列式的几点注记

Some Notes on the Patch-test and Several Nonconforming Finite Element Formulations

从分片试验条件出发,讨论了几种平面弹性非协调有限元列式,说明了理性元、自由列式和精化直接刚度列式之间的相互联系。

Based on the patch-test requirement, some formulations of non-conforming elements were discussed, and the relationship among rational element, free formulation and refined element formulation was expounded.
