Аннотация
The methods of determining strain-hardening exponent n using dynamic indentation data with allowance for loading conditions, namely, the energy before an impact and the indenter parameters, are considered. The values of n that are characteristic of impact interaction with materials having various hardnesses (steel, aluminum, copper) are obtained and compared with the values measured in static indentation. n is found to depend on the strain and the strain rate.
