An e$cient assumed strain triangular solid element is developed for the analysis of plate and shell structures. The "nite element formulation is based on the two-"eld assumed strain formulation with two independent "elds of assumed displacement and assumed strain. The assumed strain "eld is carefull

## Abstract A formulation for 36‐DOF assumed strain triangular solid shell element is developed for efficient analysis of plates and shells undergoing finite rotations. Higher order deformation modes described by the bubble function displacements are added to the assumed displacement field. The ass
