Povzetek: A formulation of hyperelastic and elasto-plastic constitutive relations for shells is discussed in this study. It is shown that many of the existing finite element implementation oriented non-linear shell models have a common base. Many of the models known from the literature are in fact just a special case of a general model. As such, the conventional (the simplest possible) large deformation shell theories are directly applicable only for small strain constitutive relations. By assuming that the deformation process of relatively thin shells is sufficiently well described by a family of conventional five-parameter theories, the thin shell constitutive relations for small strain elasticity, small strain elasto-plasticity and large strain elasticity are derived. In particular, classical St. Venant-Kirchhoff model, Green's orthotropic model of the first order, elasto-plastic model based on von Mises yield criterion and isotropic hardening and Ogden material model are considered in the context of large deformations of relatively thin shells [COBISS.SI-ID 74343]
