Mechanical-Thermal Responses of Explosive Charge Filled in Projectile During Penetrating Concrete Target

This paper is devoted to developing a viscoelastic-plastic model with a pressure-hardening strength model and a crushable pressure model for explosive charge filled in projectile when the charge penetrates concrete target. The results show that the plastic strain of the center of the arc of the charge reaches 32% due to the convergence of stress wave. Moreover, the friction between the charge and the inner wall of the body makes a certain contribution to the heating of the charge, which can provide some foundations for projectile and explosive charge structure design.
