Many plane stress finite elements which can exactly represent rigid-body and constant-strain modes are too stiff in their response to the simple flexural action of a beam. This problem has received considerable interest. This paper explores a new interpretation of the problem and shows that the poor bending response of the original 4-node plane stress quadrilateral can be quantitatively predicted by an error model.
