| Abstract | Based on the expanding cavity model, a new expression of hardness has been proposed, which suggests that hardness is determined by the ratio of the iso-stress surface size r to the indentation depth h. In combination with the experiment results and the finite element modeling analysis, we proved that the size independent hardness for geometrical similar indenter is fundamentally due to the similarity of the stress distribution during the indentation process. This study first reveals the cause of size-independent hardness for geometrical similar indentation through experiments and theoretical analysis without considering the complex constitutive models.
