Shell kinematics is quite complex. Every shell position has a shell director. Shell deformations are derived from shell displacements by their derivatives with respect to spatial coordinates. Strains have to be related to stresses to derive a structural resistance. The concept of Cauchy stresses is used for continuum‐based shell formulations in contrast to beams and slabs. A rectangular slab element of constant thickness is considered as a special case of the general shell element. The layer model is also suitable for continuum‐based thin shells.
