We derive the model of homogenized von Kármán shell theory, starting from three dimensional nonlinear elasticity. The original three dimensional model contains two small parameters: the oscillations of the material ϵ and the thickness of the shell h. Depending on the asymptotic ratio of these two parameters, we obtain different asymptotic theories. In the case h ≪ ϵ we identify two different asymptotic theories, depending on the ratio of h and ϵ2. In the case of convex shells we obtain a complete picture in the whole regime h ≪ ϵ.
