On two SiC ceramics and a standard fused silica specimen, depth-sensing indentation tests with a Berkovich indenter were carried out at several peak loads. The loading part of the load-displacement curves were statistically analyzed and it was shown that the loading exponent of the relation P∝hn was lower than the expected value of 2 in most of the cases. Factors affecting the loading exponent have been considered and evaluated. It was demonstrated that their effect was minimal on the fitting results.

Abstract
On two SiC ceramics and a standard fused silica specimen, depth-sensing indentation tests with a Berkovich indenter were carried out at several peak loads. The loading part of the load-displacement curves were statistically analyzed and it was shown that the loading exponent of the relation P∝hn was lower than the expected value of 2 in most of the cases. Factors affecting the loading exponent have been considered and evaluated. It was demonstrated that their effect was minimal on the fitting results.File in questo prodotto:
