Abstract

Abstract: This paper presents a new three-dimensional(3D) meso-structure modelling method, the anti-penetration performance of concrete target with aggregate is studied. Firstly, the shape, size and characteristics of random distribution of concrete aggregates are considered, a new meso-model generation algorithm is proposed, which is in accordance with the actual gradation and actual volume ratio of aggregates. Then, the finite element model was generated using a mapping algorithm. Finally, the influence of aggregate volume ratio on the anti-penetration performance is analyzed by simulating different concrete target models. The results show that, under the premise that the aggregate gradation of the concrete is continuous gradation and randomly distributed, when the volume ratio of aggregates increases, it will have a significant impact on the penetration speed of the projectile.
