TLDR
In this paper, a model for the interpretation of hardness tests performed on coated materials is proposed, where the substrate and layer materials are assumed to be rigid-perfectly plastic, minimization of the plastic work rate is used, and the calculation is done incrementally.About:

Finite element analysis of the critical ratio of coating thickness to indentation depth for coating property measurements by nanoindentation
TL;DR: In this paper, the critical ratios of coating thickness to indentation depth at which the substrate has various degrees of effect (2% and 10%) on the indentation response of the layered systems were discussed.
Journal ArticleDOI
Investigation of the mechanical properties of thin films by nanoindentation, considering the effects of thickness and different coating–substrate combinations
TL;DR: In this paper, two kinds of films on different substrate systems have been tested with a systematic variation in film thickness and substrate characteristics, and the resulting data are analyzed in terms of load-displacement curves and various comparative parameters, such as hardness, Young's modulus, unloading stiffness and elastic recovery.

Nanoindentation identifications of mechanical properties of Cu6Sn5, Cu3Sn, and Ni3Sn4 intermetallic compounds derived by diffusion couples
TL;DR: In this paper, Young's moduli and hardness of intermetallic compounds (IMCs) measured by nanoindentation were reported, implying that these polycrystalline IMC aggregates are rather isotropic.

Nanoindentation of amorphous aluminum oxide films I. The influence of the substrate on the plastic properties
TL;DR: In this paper, the elastic modulus of composite film/substrate systems of amorphous Al2O3 thin films, with the thickness ranging from approximately 3 nm (native oxide) to 300 nm on aluminum and sapphire substrates, were studied.
Journal ArticleDOI
Substrate effects on indentation plastic zone development in thin soft films
TL;DR: In this paper, the authors used nanoindentation and atomic force microscopy (AFM) to measure the extent of plastic pileup, which is a measure of the plastic zone radius in the film.

The mathematical theory of plasticity
TL;DR: In this paper, the solution of two-dimensional non-steady motion problems in two dimensions is studied. But the solution is not a solution to the problem in three dimensions.

TL;DR: In this paper, a simple technique is presented to obtain the characteristic microhardness values of surface coatings that are too thin for the values to be directly measured, using a physical model of film deformation during indentation.

TL;DR: In this article, a new model relating the mechanical properties of the coating and substrate materials to the experimentally observed hardness-indentation size behavior is presented and the information resulting from this approach is discussed.
