Notes:
From a unified viewpoint, this article establishes the practical and general constant stress patch test conditions (PTC) for analysing and ensuring convergence or robustness of some multivariable finite element (MFE) formulations, such as hybrid-mixed and incompatible element formulations. The proposed PTC are applied to develop new general MFE formulations which pass PTC and a family of corresponding MFE for stress analysis. Several numerical examples are also given. © 1997 John Wiley & Sons, Ltd.
