Abstracts

EN

The elastic finite element computations of the indentation process with the Berkovich indenter are performed to examine the effect of cubic crystal and indenter orientation on indentation moduli of anisotropic material. Three metals with a cubic crystal lattice and various degree of elastic anisotropy from 1 to 9 are studied: tungsten, AISI 304 steel and β -brass. Differences in anisotropy ratios expressed by the Young moduli on the one side and by the indentation moduli on the other side are quantified.
