摘要
The extreme local interaction between the projectile and target will cause mass erosion of the projectile during high-speed penetrating, and then decreases penetration performance of the penetrator. Aggregates in the concrete target will affect mass loss of the projectile obviously. Analysis about the experimental data is conducted to further discuss the effect of concrete aggregate on mass loss of the residual projectile after high speed penetration into concrete target. By assuming the concrete as a two-phase composite composed of mortar and aggregate and introducing the volume fraction and shear strength of aggregate instead of the aggregate Moh's hardness, a modified engineering model is presented to predict the mass loss of projectile by giving a dimensionless modified factor β affected by aggregate. The modified model is in good agreement with available experimental data and can better characterize the effect of aggregate on the mass abrasion of penetrator into concrete target.
