Description	Nanoindentation is widely used for the assessment of micromechanical behavior of multiple phases within the material microstructure. Evaluation is often restricted to isotropic linearly elastic solids compared to engineering macroscopic tests in which stress–strain curves are analyzed to find variety of constitutive parameters (e.g. viscous, plastic). In this paper, we identify, in addition to the elastic properties, also inelastic properties that can be directly deduced from the load–depth curve of a spherical indentation test through formulations of the effective indentation strain and stress. The accuracy of the determined material properties derived from spherical indentation depends on the accurate knowledge of the indenter shape. Therefore, calibration and determining the exact geometry of the spherical tip compared with a conical tip is described in details.
