Abstract
Stripe phases are a common pattern of self-organization forseveral soft materials. These materials are observed to undergobuckling instability when subjected to tensile stain. In this paper,buckling in layered materials is studied through the analysis of the Euler-Lagrange equation related to the deformation energy of the system. In the limiting case of thin cell,substantial differences are found with respect to the classical results obtained by Clarkand Meier \cite{ClMe73}. Furthermore,numerical analysis of a finite specimen of material is performed.
