Povzetek: A nonlinear finite elemente formulation for thin elastic shells is extended to include plasticity. Constrained three dimensional elastoplastic constitutive equations are used for the purpose. Stress resultants are obtained with through-thickness numerical integration. A return mapping algorithm is adopted for the integration of constitutive equations. Systematic linearization of the algorithm, leading to the consistent elastoplastic tangent modulus is performed. A numerical example is presented to illustrate the formulation [COBISS.SI-ID 82279]
