Indentation Curves in Viscoplastic Alloys: Mathematical Model, Fitting Procedures, and Application to the Room-Temperature Creep of an Al-Sn Alloy

Table 1

Mean value and standard deviation of obtained from individual fitting of the curves before and after data correction on steel and brass calibration blocks. The standard deviation of the curves is reduced by a factor of 3.9 for steel and 4.7 for brass.
