Morphological instability of strained surfaces In a first part, the mechanical instability of strained thin films deposited on a substrate is briefly presented in the framework of an appropriate theory of elasticity. We also discuss the difference with three dimensional patterns and how these structures can be experimentally observed.
In a second part, the post-critical evolution of the buckling patterns is numerically analyzed by means of finite elements simulations. Finally, the evolution of the vicinal surface of gold crystals deformed by external uniaxial compression is analyzed.
