Abstract
From a unified viewpoint, this article establishes the practical and g eneral constant stress patch test conditions (PTC) for analysing and e nsuring convergence or robustness of some multivariable finite element (MFE) formulations, such as hybrid-mixed and incompatible element for mulations. The proposed PTC are applied to develop new general MFE for mulations which pass PTC and a family of corresponding MFE for stress analysis. Several numerical examples are also given.
