We study theoretically the emergence of nanostructures in stressed multilayers. A non-linear amplitude expansion provides us with a simple argument on how the nanostructures emerging at the interfaces of the materials should behave. The criterion is simply expressed in terms of the relative elastic hardness of the solids. This study should serve as a guide to design new nano-architectures, a problem of much current interest.
