Various formulations for C structural finite elements are discussed. By means of two examples, a linear beam and a triangular plate element, it is shown that the proper decomposition of the deformed configuration into its bending and shear modes is essential for the effective performance of C elements. It is also shown that reduced integration can only be successful if it is equivalent to this decomposition.
