An available mathematical solution of ring compression with bulge formation was used to calibrate ring test specimens on the basis of constant interface friction factor, m. Calibration curves for the 632 Outside Diameter Inside Diameter Thickness and other ring geometries were obtained by mathematical computation and a method was established for calibrating all ring geometries with bulge formation. Calculated calibration curves of the 632 ring showed very good correlation with experimentally determined interface friction factors, m. The investigation demonstrated that a valid mathematical solution of ring compression can be used for more accurate and less laborious calibration than experimental calibration of ring test specimens.
