DYNAMIC INDENTATION OF ALUMINA CERAMICS

ВЕСТНИК ПЕРМСКОГО УНИВЕРСИТЕТА. ФИЗИКА, 2016
The paper is devoted to investigation of oxide ceramic mechanical behavior during penetration of diamond conical indenter at different time duration of the process: from ~80 microsecond to ~100 second in order to determine material sensitivity to the loading rate. Static indentation was  produced with Testometric loading machine.
