| Abstract: | Enough intensity of the cartridge case is the important guarantee of pellet's safety in the case of pressing powder and discharging. In this paper, the distribution of stress in the thin-walls cartridge case is analyzed and computed in the case of pressing powder by constructed FEA's model. At the same time the stress is obtained by the means of strain gages experimental measurement on the cartridge case during pressing powder. The cartridge case's structures intensity and deformation can be calibrated exactly according to the above method. |
