| Abstract: | Several scaling laws in the micro-indentation measurements of film-substrate structures are discussed in the present paper by a dimentsional analysis. Sequential cognition for the mechanical parameters of films (such as the elastic modulus and yielding stress of films) is outlined incorporating with the axe-symmetrical elastic-plastic finite element analysis for the micro-indentation processes. |
