    Abstract
  • According to characteristic of secondary debris, initial models of secondary debris are built. The models of secondary debris are classified as three patterns. The first patten is that the projectile is not fragmentated. The second patten is that the projectile is not entirely fragmentated. The third patten is that the projectile is entirely fragmentated. The secondary debris deceleration process is analyzed based on hydrodynamics theory and gas-solid two phase flow theory. The computational model of secondary debris deceleration is built. The computational results are consistent with numerical results very well. The model of secondary debris deceleration is validated.
