查询词典 indenter

It is shown that the Nix-Gao relation between the microindentation hardness and indentation depth holds for all the six indenter angles. The effect of friction is negligible for relatively flat indenters (e.g., Berkovich indenter), but may be significant for sharp indenters (e.g., cubic indenter).
