Dynamic response of high-speed projectiles penetrating into concrete target by asymmetric load

In this work the constraint function of concrete was regarded as the distribution load associated with the transverse load, and the yield response of projectiles under the compressive and bending load was studied using the free-free beam theory, with the main parameters of the impact of the asymmetric transverse load examined. It was found that the projectiles can be easily bent as a result of greater asymmetric mass loss, greater difference in static resistance between the grout and the aggregate, and sharper projectiles, and projectiles subjected to the transverse impact load can be considered as the response of the cantilever beam without an axial constraint. In addition, the diabasis of the plastic hinge and the formation process of the J-shaped trajectory was analysed.
