摘要

We use the finite element software ANSYS to verify the explosion experiment about whether the projectile shell contains brittle zone, and the brittle with different width and depth to improve the fragmentation rate and lethality of shell material about 50SiMnVB. The simulation results show that the shell with a brittle zone is more explosive than with out's; Within the allowable range, the bigger width of the brittle zone, the more uniform broken shell, the greater the projectile damage; the deeper depth of the brittle zone, the more easily the shell be broken, and fragment size close, the greater the projectile damage.
