Abstract
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. In this paper we explore a new interpretation of the problem and show that the poor bending response of the original 4‐node plane stress quadrilateral can be quantitatively predicted by an error model.Keywords
