Abstract：In this paper, a new scheme to formulate the 12 DOF rectangular element for analyzing of the thinand thick plates was proposed. In this method, a thin plate bending element was first formulated based onKirchhoff theory; The shear strain and complementary rotation fields were then included in the element sothat it was valid for the analysis. The result shows that as the plate become progressively thinner, the shearstrain and complementary rotation fields approach zero automatically, and the element is free of shear lock-ing. Three 12 DOF rectangular thin and thick plate bending elements were formulated by this method. Nu-merical examples indicate that these elements have the advantages of high accuracy, good convergence andstability.
