Abstract

Abstract

In order to study the penetration law of the mesoscale concrete target, The LS-DYNA software is used to simulate the penetration of rigid projectiles into two-phase concrete target. The results show that the main factors affecting the penetration resistance of the target are mortar type, coarse aggregate type and coarse aggregate volume fraction. The resistance of mortar in concrete target is close to the same part of mortar in mortar target. The resistance of coarse aggregate in concrete target is much lower than the same part of rock in rock target. By extending the Forrestal resistance equation, the penetration depth model of mesoscale concrete is established, which is in good agreement with the numerical simulation.
