“…Within this objective, a variety of models describing the contact area function have been developed [20,[40][41][42][43][44][45][46][47]. In nanoindentation, the complex area function expressing the contact area as a function of the contact indenter displacement is probably the most used: where C 1 through C 8 are constants.…”

“…[14][15][16][17][18][19][20][21] Instead of Eq. (1), two approximations of the loading curve have been elaborated: fitting by (i) power law or (ii) second-order polynomial.…”

“…The most important surface mechanical property that defines the contact resistance of alumina is its hardness. Therefore, it is not surprising that hardness evaluation at various length scales consumes a significant amount of current research efforts in alumina [6][7][8][9][10][11][12][13][14]. Most of the commercially available alumina ceramics used for a variety of technical applications are coarse grained.…”

“…They exhibit low to moderate hardness and, in addition, characteristically exhibit an R-curve behaviour which means that their crack growth resistance improves as the crack grows. In spite of the wealth of literature that exists on hardness of alumina measured at macro-, microscale [10][11][12], or nanoscale [13,14] mostly for fine grain and/or submicrometer grain-sized alumina ceramics; however, the reports on hardness behaviour of dense coarse grained alumina ceramics are really rare [10]. It is important to recognize that depth sensitive indentation technique has emerged as a very effective technique to determine the surface mechanical properties of wide variety of materials [15][16][17][18][19].…”
