“…Li and chen (2003) proposed formulas for predicting the penetration depth of concrete impacted by a hard projectile based on dimension analysis using a theoretical penetration model. Some studies have investigated the impact resistant behavior of RC structures as a function of moderate velocities in the range of 10–150 m/s (Ito et al, 1995; Li et al, 2007; Yankelevsky et al, 2000). However, few formulas have been proposed based on the detailed failure mechanism of RC slabs subjected to projectile impact on the basis of measured tests and numerical analyses.…”

“…In these studies, the overall response of RC slabs (flexure and punching shear failures) was investigated at an impact velocity of less than 10 m/s. The local damage of RC slabs subjected to a highvelocity impact of 150-1000 m/s was investigated for bullet and aircraft collisions (Beppu et al, 2008;Chang, 1981;Chen et al, 2008;Gomez and Shukla, 2001;Huang et al, 2005;Hughes, 1984;Ito et al, 1995;Kennedy, 1976;Li and Chen, 2003;Li et al, 2005Li et al, , 2007Werner et al, 2013). These studies reported that a local failure occurred in the vicinity of the collided part because of the stress wave interaction and local deformation.…”

This study aims to investigate the local failure mechanism of reinforced concrete slabs subjected to hard and deformable projectile impacts. This is done by conducting impact tests and numerical simulations. In a series of impact tests, a hard/deformable steel projectile (8.3–8.4 kg) collided with a reinforced concrete slab with a thickness of 10–30 cm at an impact velocity of 64–90 m/s, and the impact and reaction forces were measured. The numerical simulation demonstrated that the failure of the reinforced concrete slab was affected by the rigidity of the projectile in terms of the maximum impact force and impulse.

This study investigates the failure characteristics of reinforced concrete slabs subjected to moderate-velocity impacts by conducting impact tests and numerical simulations. In a series of tests, a spherical steel projectile with a mass of 8.3 kg and a diameter of 80 mm is collided with an reinforced concrete slab at an impact velocity of 65-90 m/s. To investigate the failure characteristics of the reinforced concrete slab, impact motion of the projectile, reaction force, and strain-time history on the back surface and reinforcing bars of the reinforced concrete slab were measured. Failure modes obtained experimentally were compared with the Central Research Institute of Electric Power Industry formula proposed for the local damage of reinforced concrete slabs. Test results revealed that a circular scabbing crack on the back surface of the reinforced concrete slab was completed while there is a sharp increase in the reaction force. Numerical simulations using a high-fidelity concrete model reasonably reproduced the failure characteristics of an reinforced concrete slab. Numerical results demonstrated that the scabbing failure of an reinforced concrete slab subjected to a moderate-velocity impact was initiated by the penetration of the projectile and was completed during the reaction force response.
