  • In this paper, the influence of the aspect ratio on the penetration resistance in the target penetration process of the warhead was studied based on the classical cavity expansion theory, the modified Forrestal resistance model and the acceleration resistance model.The influence of the aspect ratio on the resistance term coefficient was analyzed and the range of applicability of the three theories was discussed by calculating the penetration residual velocities of the warhead with different aspect ratios.The results show that the variation of the acceleration resistance term coefficient has a significant influence on the penetration process when the aspect ratio is below 3;when the aspect ratio is above 5, the results of the three models tend to converge, and they are all applicable to engineering calculation.
