    In this work we derive and mutually compare several 4-node shell hyperelastic finite elements for large deformation analysis. The elements are based on Reissner-Mindlin shell theory. They use the enhanced assumed strain (EAS) concept for enhancement of membrane and bending displacement-compatible strains and the assumed natural strain (ANS) concept for treatment of transverse shear strains. The elements differ from each other by the number of membrane and bending EAS parameters. An optimal number of these parameters is suggested on the basis of numerical results.
