Abstract
A new finite-element approach to calculating the hardness of nanocomposite materials based on a 316L stainless steel matrix and nanoceramic inclusions is presented. Two different ceramic inclusions, alumina and titania, are considered. The finite-element model is created on the basis of the spherical Brinell hardness contact model. A quarter of the 3D finite-element is used to model the contact between a spherical tungsten carbide indenter and nanocomposite materials. The effect of the elastic modulus and percentage of the ceramic inclusions on the hardness of the nanocomposites considered is investigated. The finite-element model is verified by comparing its results with experimental data. The comparison showed a good agreement for low-concentration compositions and a slight deviation for highly concentrated ones.
