Indentation as a method to characterize materials has a history of more than 117 years. However, to date, it is still the most popular way to measure the mechanical properties of various materials at microscale and nanoscale. This review summarizes the background and the basic principle of processing by indentation. It is demonstrated that indentation is an effective and efficient method to identify mechanical properties, such as hardness, Young's modulus, etc., of materials at smaller scale, when the traditional tensile tests could not be applied. The review also describes indentation process via both experimental tests and numerical modelling in recent studies.

“…The hardness test also allows us to evaluate the reduced Young’s modulus of the material tested according to the contact area and the measured unloading compliance: E=1βπ2C1A,where A is the contact area (mm 2 ), C (mm·N −1 ) is the compliance, β is a correction factor which depends on the indenter’s geometry, where β varies in the range 1.01–1.07 for Vickers indenter [9,11].…”

“…Another characteristic of load-unload curves is determination of uniaxial mechanical properties, such as yield stress and the strain hardening exponent n [9,25]. Johnson [26] found that hardness of ductile elastic-plastic materials is expressed by: ϕ=Eσrtanα,where E (MPa) is Young’s modulus of the material, α (rad) is the angle of inclination of the face of the indenter to the surface of specimen and σ r (MPa) is the representative stress associated to the representative plastic strain ε r [26]: εr=tanα5.…”

Three-dimensional finite element-based numerical analysis of Vickers indenter hardness test was conducted to investigate the effect of frictional conditions and material anisotropy on indentation results of deep drawing quality steel sheets. The strain hardening properties and Lankford’s coefficient were determined through the uniaxial tensile tests. The numerical computations were carried out using ABAQUS nonlinear finite element (FE) analysis software. Numerical simulations taken into account anisotropy of material described by Hill (1948) yield a criterion. The stress and strain distributions and loading–unloading characteristics were considered to study the response of the material. It was found that the hardness values seemed to be influenced by the value of the friction coefficient due to the pile-up phenomenon observed. The increasing of the friction coefficient led to a decrease of the pile-up value. Moreover, the width of the pile-ups differed from each other in the two perpendicular directions of measurement. Frictional conditions did not significantly affect the maximum force and the character of load–displacement curves. Frictional regime between the indenter and workpiece caused that the region of maximum residual stresses to be located in the subsurface.
