| Abstract: | A simple indentation technique for measuring the hardness-to-modulus ratio of elastic/plastic materials was developed. The method, which is based on measurement of the elastic recovery of the in-surface dimensions of a Knoop indentation, allows ready evaluation of the hardness-to-modulus ratio to an accuracy better than 10%. |
