L. De Fazio et al., Nanoindentation of CVD diamond: comparison of an FE model with analytical and experimental data, DIAM RELAT, 10(3-7), 2001, pp. 765-769
This paper describes an experimental procedure for the determination of the
hardness and the elastic modulus through nanoindentation of a CVD diamond
coating using simple analytical formulae. Such tests, performed with a Berk
ovich indenter, were simulated by finite element analysis. Through the nume
rical analysis, it was possible to reproduce the load-penetration depth cur
ves and thus, confirm the validity or correct the property calculations. Re
sults show that the predicted property values can be affected by the assume
d material strain hardening. By comparing the numerical values with the exp
erimental results, it is possible to characterise, with sufficient accuracy
, the material behaviour. (C) 2001 Elsevier Science B.V. All rights reserve
