Depth Sensing Indentation (DSI) is used in the mechanical characterization of bulk and coated materials. The finite element method is used to perform three-dimensional numerical simulations of Vickers hardness tests. The modelling and the optimisation of the more significant parameters in the simulation of this test are treated in detail. The load-unloading curves are carefully studied and the indentation geometry is related to the material mechanical properties. For the case of bulk materials, different reverse analysis methodologies for evaluate the stress-plastic strain curve from the...
