“…Over the past decades, many empirical or semiempirical DOP models for the projectile penetration into various materials have been opened [8][9][10][11][12] . Young 13 proposed an empirical DOP model based on a number of experimental data for the penetration of full-scale projectiles at sub ordnance and ordnance velocities into quasi-brittle materials such as concrete, rock and soil; Forrestal and his colleagues [14][15][16] also presented an semi-empirical DOP formula for an ogivalnosed projectile penetrating into concrete targets, based on the spherical cavity-expansion theory and their experimental data of sub-scale projectiles. Li & Chen 17 developed again a semi-empirical DOP formula available for the penetration of sub-scale projectiles by using dimensional analysis, in which an impact function and a geometry function are introduced for the first time.…”

A dimensionless model for the depth of penetration (DOP) of a projectile penetrating into a concrete target, based on the similarity theory involving intermediate asymptotics, complete similarity, and incomplete similarity is presented. The calculated numerical results are in good agreement with previous experimental data, including two sets of full-scale and twenty-four sets of sub-scale penetration of non-deformable projectiles into concrete targets. Moreover, compared with several empirical and semi-empirical DOP models, the new model is applicable within a relatively broader range, including the penetration of both sub-scale and full-scale projectiles. For the limitations of the validity, dimensionless parameters Π 3 =ϕ t /ϕ larger than 12, Π 4 = (ϕ 3 f c )/(Mv 0 2 ) smaller than 0.1, and the initial impact velocity of the projectile less than about 900 m/s to 1000 m/s are necessary for the model.

“…The Forrestal penetration formula (Forrestal et al, 1994;Frew et al, 1998) had the theoretical foundation of cavity expansion and was calibrated by many experiments; therefore, this formula was widely used. The penetration resistance F and penetration depth are as follows:…”

Deep penetration experiments were performed on five types of concrete with different coarse aggregate content. The projectile diameter was 29.9 mm, the initial velocity was 647 m/s, and the volume fraction of the coarse aggregate was between 0% and 59.0%. The damage laws and damage mechanism of the target were analyzed. The pure mortar target had the smallest radial crack origin diameter and crater depth. Too high of the coarse aggregate content led to the formation of many voids, which led to the disappearance of radial cracks, crater surface bypassing the coarse aggregate and a large reduction of crater diameter. The influence laws and mechanism of the coarse aggregate on the penetration depth were also analyzed. The increase of volume fraction of coarse aggregate was beneficial to reducing penetration depth and the increase of voids volume fraction was opposite. The penetration depth was the lowest when the volume fraction of the coarse aggregate reached the maximum and no voids formed. By modifying the static resistance stress in the Forrestal penetration formula, a penetration depth model considering the volume fractions of the coarse aggregate and voids was established. The predicted results were in good agreement with the experimental results.

Abstract. This paper presents numerical analysis result of projectile penetration with concrete target. We applied dynamic material properties of 4340 steels, aluminium and explosive for projectile body. Dynamic material properties were measured with static tensile testing machine and Hopkinson pressure bar tests. Moreover, we used three concrete damage models included in LS-DYNA 3D, such as SOIL CONCRETE, CSCM (cap model with smooth interaction) and CONCRETE DAMAGE (K&C concrete) models. Strain rate effect for concrete material is important to predict the fracture deformation and shape of concrete, and penetration depth for projectiles. CONCRETE DAMAGE model with strain rate effect also applied to penetration analysis.Analysis result with CSCM model shows good agreement with penetration experimental data. The projectile trace and fracture shapes of concrete target were compared with experimental data.
