| 摘 要： | 本文通过定义非协调位移元的单元特性函数,提出了一种建立非协调元与广义杂交元之间的等价关系的一般方法,进一步证明了两种有限元模型之间存在强等价性,为两种单元模型的构造提供了相互借鉴的理论依据和有效的准则。

| Abstract: | In this paper the identity of all the incompatible displacement and generalized hybrid elements is proved by defining the element property functions of incompatble displacement element and proposing a general way for establishing the identity, so that the two models can help each other in stiffness matrix generation and stress computation. |

| Keywords: | incompatible displacement element element property function generalized hybrid element identity |
