Equations for stresses in a laminated orthotropic curved beam based on the technical theory assumption (Winkler) are presented. The formulation of the same problem by orthotropic elasticity is indicated. In order to assess the applicability of the technical theory over a range of material properties and geometries, the specific case of a three-layer beam was studied. Results of the technical theory were compared with those using elasticity. The dependence of the geometrical and mechanical properties of the individual layers on the stresses and displacements is shown. Some interesting results are shown with the aid of numerical examples.
