In this paper, the quasi-static perforation of plates and tubes were calculated. In the calculation, the punching speed for quasi-static analysis was 2 mm / min, the punches were assumed to be rigid body for saving the CPU time, and the Johnson-Cook model was adopted as the constitutive law for the material of plates and tubes. The results showed that the punching loads were increased with the stroke for the three different puncher, and reduced after the objects were perforated. The maximal stresses for the cases were with the similar behaviors as punching loads. 方亮彬 2013 學位論文 ; thesis 68 zh-TW |
