“…A three-sided Berkovich diamond indenter tip was used with a total included angle of 142.3°. As mentioned by several authors [14,17], indentations using a Berkovich indenter result in the same force vs. displacement curve as a conical indenter with a half apex angle θ = 70.3°. This is the reason why various authors have preferred to simplify numerical modeling using a 2-D axisymmetric mesh with a conical indenter instead of a 3-D Berkovich one.…”

“…Pelletier et al [17] showed that the numerical modeling of the curvature of the indenter tip has an influence on load vs. displacement curves. He found that a more realistic model of that curvature leads to results in better agreement with experimental ones.…”

“…From the load vs. displacement results obtained with these three tips, it appears that a decrease in the sharpness of the simulated indenter tip provides an increase in the maximum load, for the same indentation depth. Pelletier et al [17] has also shown the necessity of taking the curvature into account to better simulate the experimental results.…”

This paper focuses on the numerical modeling of nanoindentation tests. The first goal of this study is to collect essential material parameters and boundary conditions from the literature and to complete the data required to accurately model nanoindentation tests. The second goal of this study consists in validating the material parameters identified from macroscopic tensile tests of the body-centered cubic β phase of Ti-5553, a new generation of titanium alloy. This validation is performed looking at experimental and numerical nanoindentation curves obtained for different grain orientations.

“…Hardness of foils is quite different from hardness of bulk material which is about 1.77 GPa for bulk copper [16] and 0.84 GPa for bulk zinc [16]. These differences are due to size effect.…”

“…The results are summarized in Table 1. Elastic moduli of foils are inferior to moduli of bulk materials which are equal to 145 GPa for pure copper [16] and 84 GPa for pure zinc [16]. This point is quite surprising since several studies during last decades have shown that thin films tend to exhibit similar Young's modulus that bulk material [3,5].…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. The aim of this work was to determine the ability to produce thin metallic foils by self-induced ion plating. Foils of pure copper and pure zinc with a thickness of 35 µm have been successfully produced and their characteristics have been compared to foils obtained by conventional techniques (i. e. electroplating and rolling). Results show the following: (i) more or less compact microstructures can be obtained by self-induced ion plating depending on gas pressure and substrate temperature; (ii) microstructures obtained by self-induced ion plating are quite different from those obtained by electroplating and rolling; (iii) Young's modulus depends on foils roughness; (iv) hardness depends on grain size by exhibiting a Hall-Petch behavior in the case of copper foils and an "inverse" Hall-Petch behavior in the case of zinc foils.
