Abstract: Kick's law and modified Kick's law are emperical relations, indeed useful in carrying out the analysis of the variation of indentation dimensions (d) with applied load (p). However, it could not predict the range of applied loads within which the orientation-dependent straight line is not valid. The present study indicates that the nonlinear portion in the plot of P/d^{2} vs 1/d corresponds to the intermediate load region (ILR) in addition to LLR and HLR, which could not be traced out from the study of Kick's law and modified Kick's law. The implications are discussed in delatil.
