- Abstract
This paper investigates the intrinsic mechanisms of the scaling effect in concrete penetration, validated by a high-velocity experiment. We identify fixed-size coarse aggregates as the fundamental cause for the breakdown of geometric similarity, which leads to this effect. A 2D mesoscopic finite element model, explicitly describing random aggregates, was developed to study this phenomenon. Numerical simulations successfully reproduced the key observation: dimensionless penetration depth increases with projectile scale. Furthermore, the study reveals that aggregate particle size is a more significant influencing factor than its strength.
