AB - By following the geometric point of view in mechanics, a novel expression of the com- bined hybrid method for plate bending problems is introduced to clarify its intrinsic mech- anism of enhancing coarse-mesh accuracy of conforming or nonconforming plate elements. By adjusting the combination parameter $\alpha \in (0,1)$ and adopting appropriate bending moments modes, reduction of energy error for the discretized displacement model leads to enhanced numerical accuracy. As an application, improvement of Adini’s rectangle is discussed. Numerical experiments show that the combined hybrid counterpart of Adini’s element is capable of attaining high accuracy at coarse meshes.
