“…In general, an experimental loading curve can be fitted more accurately than an unloading curve with the help of equation (6). Approximation of an unloading response by equation 6very much depends on the type of material; the smaller the value of elastic work, the better is the fit [35]. The elastic energy constant may also be used to determine the depth along which the contact is made between the material and the specimen, which is given by [27]:…”

Normalized indentation works, referred to as the total and elastic energy constants, have been shown to be effective in the representation and analysis of experimental load-displacement data. However, their physical meaning, influencing factors, variation range and relationships with other nanomechanical quantities are not precisely known. In this study, the load-displacement data obtained as a result of simulations of elastic and elasto-plastic indentations are extensively analysed to enhance our understanding concerning these two energy-based parameters. It has been shown that while the total energy constant describes the state of an indenter tip and the type of contact regime, the elastic energy constant characterizes the response of a material to indentation. In addition, their applications in the evaluation of key nanomechanical quantities such as the indenter tip radius, the nominal hardness and the contact depth are also discussed.

“…between the experimental and theoretical curves could be seen. However, the approximating power of unloading curves depends on the type of material; for harder material, only initial portion can be modeled accurately [70][71]. if the phases are perfectly distributed, the probability of indenting each phase is equal to the volume fraction of the phases present.…”
