Two methods for evaluating tapping inspection aptitude of retort sterilized can body, Air Injection Method and FE Simulation Method, were developed. Optimum can bottom shape was investigated by the Statistical Design Support System combined with the FE Simulation Method. Depth of annular bead and bottom curvature were found to be dominant for each characteristic value. Evaluation results of the characteristic values for these optimum shapes by the FE Simulation Method and the Air Injection Method indicated qualitative consistency with those expected by optimization, and showed the improvement of tapping inspection aptitude of retort sterilized can body, as expected.
