Abstract: 

In this research the effect of the tumbling perforation of blunt-faced cylindrical projectiles in moderately thick aluminum plates is presented. The perforation process – depend on the impact angle in normal and oblique impact - consists of four stages: erosion, plugging, hole enlargement and petaling. The modeling in the plugging stage consists sequentially of cratering, plug formation, plug separation, plug slipping and post perforation deformation. In this analytical model, the target material is considered to be rigid perfectly plastic, while the projectile is regarded as adeformable. material Projectile deformation depend on relative velocity of projectile occurs in three mode: erosion, flattening and rigid projectile. The effect of the frictional force is considered too. The new analytical results were found to be in good agreement with experimental results.
