A study on the resistance of rigid projectiles penetrating into semi-infinite concrete targets is performed in this paper. Experimental data are analyzed to examine the penetration resistance during various stages of the penetration process. A numerical tool using AUTODYN hydrocode is applied in the study. The numerical results on both deceleration-time history and depth of penetration of projectiles are in good agreement with experimental data, which demonstrate the feasibility of the numerical...

Abstract For effective structure and personnel protection against projectile impact, accurate prediction of the depth of penetration (DOP) of projectile into concrete is essential. Many empirical and semi-empirical formulae have been developed to yield accurate predictions as compared with testing data. In most of these formulae, the concrete target was assumed as homogeneous and the mechanical properties of concrete material were characterized by the compressive strength of concrete. The deviat...

Abstract Analyzing mechanical behavior at the mesoscale level should be a powerful tool for higher heterogeneous materials like concrete. In this study, the mechanical and damage analysis of concrete were investigated using a 3D mesoscale model under complex loading. A less time-consuming method was proposed for constructing the realistic mesostructure of concrete. The finite element simulation showed good agreements with the uniaxial and biaxial experimental results. Then complex loading condit...

The mechanical performance of concrete is strongly influenced by the geometry and properties of its components (namely aggregate, mortar, and Interfacial Transitional Zone (ITZ)) from the mesoscale viewpoint, and analyzing the material at that level should be a powerful tool for understanding macroscopic behavior. In this paper, a simple and highly efficient method is proposed for constructing realistic mesostructures of concrete. A shrinking process based on 3D Voronoi tessellation was employed...

Abstract It is very important to minimize the residual velocity of penetrator as far as possible in designing defensive structures. The ability of reinforced concrete (RC) against projectile penetration can be effectively promoted by optimizing the configuration of reinforcement. This paper presents numerical studies on the penetration resistance of RC against non-deforming projectile penetration at striking velocities ranging from 300 m/s to 1056 m/s. Firstly, an innovative three-dimensional (3...

Abstract An effective numerical method is proposed in this paper to generate a meso-scale composite model of reinforcement concrete (RC) which contains aggregates with random size and shape based on Voronoi tessellation method. Besides the randomly distributed aggregates, the present model takes into account the reinforcement, compared with other conventional methods in finite element modeling of concrete. The shrinking algorithm with random shrinking factors is employed to generate graded aggre...

Abstract During high speed penetration into concrete targets, projectiles will suffer different degrees of mass loss, which will generate severe changes in nose shape and significantly decrease the efficiency of penetrators. In this study, a semi-empirical model is developed for predicting the mass loss and nose shape change, in which thermal melting of projectile materials generated by friction work is considered as the primary mechanism of mass loss. The dynamic friction between the target and...
