Homogenized moderately wrinkled shell theory from 3D Koiter's linear elasticity

preprint2026arXivOpen access

Abstract

In this paper we derive, by two−-scale convergence, periodically wrinked shell models starting from three dimensional linear elasticity, depending of the behaviour of the small parameter ε>0\varepsilon>0 and p>1p>1, differents theories appear. We assume that the mid-surface of the shell is given by $\displaystyle ψ(x_1,x_2)+\varepsilon^pθ\left(\frac{x_1}{\varepsilon},\frac{x_2}{\varepsilon}\right)\vect{a}_{3}(x_1,x_2)$, where θθ is [0,1)2[0,1)^2-periodic function and p=2p=2. We also assume that the strain energy of the shell has the Koiter's model.
