The aim of this chapter is to study the effect of crystalline substrate plasticity on thin film buckling. A general description of buckling is given first within the framework of the Föppl–von Kármán theory of thin plates. The model is then used to describe the buckling induced by plasticity of the crystalline substrate. The localization of the buckling structures on the areas of dislocation emergence is explained. Finally, the model is generalized in order to obtain all the equilibrium states of a deformed thin film ...
