Hardness is commonly used to characterize ceramics at a single load or over a range of loads in order to study the indentation size effect (ISE). Extensive new experimental work on ceramics suggests that hardness versus load curves exhibit a transition point to constant hardness that may be related to the brittleness of ceramics. This transition is studied and a new interpretation of the hardness of ceramics is presented. A new parameter to characterize the brittleness of ceramics is proposed.
