Abstract

New indentation hardness measurements on silicon crystals are correlated with previous results obtained over a wide range of load values to analyse the ambient-temperature cracking behaviour. From an elastic-plastic-cracking analysis of the total results, brittle cracking is reasoned to be promoted by any amount of plastic deformation occurring during the initial indenting process.
