Indentation size effect in MgO.
The indentation size effect (ISE) model of Nix and Gao overestimates the hardness of MgO for small indentations. The cause may be associated with a slight expansion of the plastic zone. If the plastic zone has an effective radius fa, experimental data indicate that f increases for small indentations and is 1.66 at zero indentation depth.
