    Abstract

    Constant loading rate divided by load (˙P/P) indentation tests have been conducted on high purity copper at room temperature. The results show that: 1) The loading curves can be fitted to a power-law relationship of the form P = Chn and the exponent n increases with decreasing P/P. 2) The hardness value itself, and its decreasing rate with depth, increase with increasing P/P. 3) A constant P/P can result in a constant indentation strain rate (h/h), even if indentation size effects (ISE) exist in the materials. 4) The relationship between P/P and h/h can be shown to be P/P = n.(h/h).
