Abstract
Alumina, acryl glass, colour paint and India-rubber have been investigated by load-indentation measurements. The data were evaluated in terms of specific deformation energy densities and in terms of the conventional hardness under load. The specific energy densities were found to indicate a constant material response to the penetration of the indentor for extended penetration depth ranges. However, the conventionally calculated hardness values show a typical decrease for increased penetration depth.
