This paper reports the measurement of 296 combinations of load, roller diameter, and plate hardness. The diameters of the steel rollers ranged from 1/16 to 4 in. inclusive. The hardness of the steel plates ranged from 42 Rc to 61 Rc. Two series of tests are also included for titanium plates having a hardness of 40 Rc and 43 Rc, respectively. Equations are derived from this experimental data which can be used to estimate the depths of permanent indentation for a large range of roller diameters, plate hardness, and loads.
