TLDR
In this article, a specific finite element simulation software, HAFILM, was developed to simulate the ultramicrohardness tests and different mesh refinements were tested because of the dependence between the values of the mechanical properties and the size of the finite element mesh.About:

Comparison between Berkovich, Vickers and conical indentation tests: A three-dimensional numerical simulation study
TL;DR: In this article, the influence of indenter geometry on indentation test results of bulk and composite film/substrate materials was investigated, in order to clarify the differences in the load-indentation depth curves and hardness values of both types of materials.

Mechanical properties of magnetite (Fe3O4), hematite (α-Fe2O3) and goethite (α-FeO*OH) by instrumented indentation and molecular dynamics analysis
TL;DR: In this paper, the properties of pure (crystal) and complex (product of corrosion) iron oxides, magnetite (Fe 3 O 4 ), hematite (α-Fe 2 O 3 ) and goethite (β-FeO·OH), were determined by means of molecular dynamics analysis (MDA) and instrumented indentation.

Probing elasticity and adhesion of live cells by atomic force microscopy indentation.
TL;DR: Force–displacement curves measured in indentation experiments performed with silicon nitride AFM probes with pyramidal tips on live cells agree well with the theoretical prediction and are used to determine the cell elasticity modulus and indenter-cell work of adhesion.

Hardness–strength relationships in the aluminum alloy 7010
TL;DR: In this paper, the relationship between Vickers hardness, yield stress and tensile strength was analyzed by combining data from two independent studies involving 7010 alloy plate and a rectilinear forging.

A new approach for reverse analyses in depth-sensing indentation using numerical simulation
TL;DR: In this paper, a reverse analysis of the Vickers indenter is proposed to determine the plastic properties of the indenter using a numerical simulation, which is based on the results of the experimental hardness tests acquired with single indenter geometry.

An improved technique for determining hardness and elastic modulus using load and displacement sensing indentation experiments
Warren C. Oliver,George M. Pharr +1 more
TL;DR: In this paper, the authors used a Berkovich indenter to determine hardness and elastic modulus from indentation load-displacement data, and showed that the curve of the curve is not linear, even in the initial stages of the unloading process.

Warren C. Oliver,George M. Pharr +1 more
TL;DR: In this article, the authors review the current understanding of the mechanics governing elastic-plastic indentation as they pertain to load and depth-sensing indentation testing of monolithic materials and provide an update of how they now implement the method to make the most accurate mechanical property measurements.

The relation between load and penetration in the axisymmetric Boussinesq problem for a punch of arbitrary profile
TL;DR: In this article, a solution of the axisymmetric Boussinesq problem is derived from which are deduced simple formulae for the depth of penetration of the tip of a punch of arbitrary profile and for the total load which must be applied to the punch to achieve this penetration.

TL;DR: In this paper, a method for obtaining hardness and Young's modulus from the data obtained from these types of instruments is described, where the elastic displacements are determined from data obtained during unloading of the indentation.
