A Dynamic Relation Model Analysis of High-speed Impact and Sabot Strength

To understand how a projectile penetrates a sabot during a high-speed impact testing, which led to the failure of the impacting experiment, a dynamic model was built based on the interactions between the projectile and the sabot; and the bearing strengths of the sabot with varying impact speeds were analyzed. The correctness of the model was verified by an experiment. It shows that, with all the other conditions kept the same, the maximum stress between the sabot and the projectile increases with the decrease of the sabot mass, the increase of the projectile and impact speed.
