DEFORMATION VERSUS LOAD RELATIONS OF TINPLATE CANS - INTERPOLATION BETWEEN EXTREME LOADING CYCLES

Extreme loading cycles were applied to tinplate cans Type 7/2-153 (V-0 = 3232 cm(3)) for measuring volume change vs. pressure difference rel ations (Delta V = f(Delta p)). The term deformation is understood as v olume change in the publication. Interpolation formulas of empirical n ature have been created for the calculation of Delta V = f(Delta p) re lations inside the domain of the extreme loading cycles. Measured and calculated results have been compared, earlier results on a can of sma ller size (V-0 = 860 cm(3)) also have been included. The ratio of the mean difference (d) between measured and calculated volume changes to the mean deviation of parallels (s) has been found between 0.91 to 4.8 1.
