Summary

Using an integral form of the Kirchhoff hypothesis a set of algebraic constraints valid in thin plate analysis and relating rotational and translational degrees of freedom of a CO element is formed. The constraints are then enforced by means of a penalty formulation. The approach yields highly accurate CO plate elements of both quadrilateral and triangular shape. Approximations of various order can be accommodated.
