Abstract

Depth sensing indentation tests were carried out in stiff ceramics like Al2O3, AlN, SiC and B4C, using a diamond Berkovich tip. The experiments show that the accuracy of the data depends on the stiffness ratio between material and indenter. An iterative calibration procedure is proposed to get a reliable estimation of the elastic modulus.
