Hard projectile perforation on the monolithic and segmented RC panels with a rear steel liner

Hard projectile impact on layered SFRHSC composite target

“…[18], the thickness of the rear steel liners were 1 mm and it was found that the improvements of the steel liner on enhancing the impact resistance of the RC/steel composite targets were not obvious. While in the present test, the influences of the 3 mm-thick rear steel liner on the terminal ballistic performance of the projectiles could not be neglected.…”

“…In Ref. [18], we have lately proposed an explicit dimensionless expression to predict the terminal ballistic parameters of the projectile perforating the bare concrete plate, which is given as follows…”

“…In Ref. [18], Eq. (1) was well validated by 25 shots of projectile perforation test on normal strength RC panels with the thickness of 100 mme300 mm and the striking velocities of 536 m/s to 737 m/s, as well as the test data from Hanchak et al [3], Cargile et al [19] and Li et al [20].…”

High-Speed Interaction Rod and Segmented Projectiles into Massive Obstacles

“…As a research tool this study uses the method of numerical simulation based on 2-step method of second order accuracy in the Euler space variables [2,[9][10][11][12][13]. When calculating penetration segmented drummer applied the algorithm combining the contacting segments after actuation of interacting with the barrier segment to the size of a few computational cells [14][15][16][17][18][19]. The introduction of such algorithm is equivalent to the procedure of changing boundary conditions on the contact surface with a perfect slip condition at the rigid couplings [20][21].…”

Investigation on Interaction of Explosively Formed Projectile with Multi-layer Medium Targets

“…In recent years, a large number of scholars investigated the intrinsic mechanisms on penetrating into concrete [1][2][3]. Nia et al [4] studied the resistance of concrete target against penetration of eroding long rod projectile.…”
