Abstract

Abstract

The stress state of the target was seldom taken into account in the investigation of the ballistic performance of cement mortar. Based on the self-developed penetration experimental system of concrete under true-triaxial confinement and the experimental results of the anti-bullet performance of cement mortar, the depth and resistance of opening pit under different stress states were discussed in the present paper. The empirical formula of penetration depth and finite element method (FEM) based on HJC model were used to analyze the penetration behaviors of cement mortar results. The results showed that under the lower velocity impact, the UMIST formula and the HJC model were both effective in the prediction of pit depth. At the same time, the stress state had an obvious influence on pit depth. With the increase of the lateral limit, the cement mortar strength increases and the pit depth of the projectile decreases. The acceleration wave in bullet and the wave in the y-axis support rod were calculated by FEM based on HJC model. The results showed that the process of projectile opening pit would be recorded by these two waveforms, and the wave structure in the y-axis support rod would be more significantly. Although the tendency of the simulation results was basically consistent with the experimental waves, there was difference in the stress amplitude to some degree, which also indicated that the calculation method of the pit opening resistance based on HJC model needed to be improved.
