Conventional shell models (e.g. of Reissner-Mindlin type) require condensation of 3d constitutive equations. This cannot be done in a case of more complex large strain hyperelastic and elasto-plastic constitutive relations. If one still wants to combine fully 3d constitutive equations with a shell model, the kinematics of conventional shell models needs to be refined. The following possible refined shell formulations will be discussed: (a) EAS (enhanced assumed strain) formulation which decomposes strains into compatible and incompatible parts, (b) EAS formulation which decomposes deformation gradient into compatible and incompatible parts, (c) refined shell formulation with seven displacement-like kinematic parameters, (d) a modified version of (c). Some numerical examples will be shown to validate each formulation.
