Abstract

Abstract: The penetration process of the earth penetration weapon (EPW) with booster into concrete targets was studied to have a deeper cognition for it, and an appropriate boosting scheme was chosen in the design of EPW. Referred to the modified Forrestal resistance model given by Ref.［7］, based on the cavity-expansion theory and considered the influences of projectile acceleration on the penetration resistance, an semi-empirical calculation formula of penetration resistance which could be used for EPW with booster was proposed. Then, in the study on EPW with booster, the penetration process into concrete targets was calculated. Compared with the experiment results, the calculation results show that the new semi-empirical formula can reflect the penetration resistance better. The research in this paper has some practicability; moreover, it can be used to guide the study of the EPW with booster.
