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.

## Abstract Based on finite element formulations for the strain gradient theory of microstructures, a convergence criterion for the __C__^0โ1^ patch test is introduced, and a new approach to devise strain gradient finite elements that can pass the __C__^0โ1^ patch test is proposed. The displacement
