Derivation of a homogenized von Kármán shell theory

Peter Hornung and Igor Velčić

Abstract

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 $\epsilon$ and the thickness of the shell $h$. Depending on the asymptotic ratio of these two parameters, we obtain different asymptotic theories. In the case $h\ll\epsilon$ we identify two different asymptotic theories, depending on the ratio of $h$ and $\epsilon^2$. In the case of convex shells we obtain a complete picture in the whole regime $h\ll\epsilon$.
