pages 469 - 474, full text

Stress and strain distribution underneath various types of indentors – spherical, conical, and Berkovich – can be provided by the finite element method. In the presented work, indentation of isotropic aluminium is introduced as a benchmark problem, in which plasticity and contact algorithms are tested. The knowledge obtained in this way passes on to the real-life indentation processes involving orthotropic materials such as FCC metals (Ni-based alloys) in the context of nonlinear continuum and finite strain elasto-plasticity, including homogenization approach on the material microscale.
