In this note, we point out that two generalized conforming triangular plate elements, namely GCⅢ-T9 and GCⅡ-T9, proposed in references [2] and [4], are identical to the familiar Specht element[3]. Moreover, another generalized conformingelement in reference [6] is proved to be equivalent to VZ1 element in [8].
In this paper, two nonconforming finite elements are discussed. They pass the generlized patch test and can be used in the numerical solution of second order elliptic problems.
