“…The penetration equations chosen for comparison were the Modified NDRC Formula, the Amman and Whitney Formula, the formula developed by Forrestal in 1994, and the Kar Formula [1,5,6]. Three of these four formulas were chosen for comparison because the experimentally measured projectile mass and striking velocities do not exceed the stated equation limitations.…”

Abstract. This paper will address the experimental results of the impact of 101.6 mm (4 in) explosively formed projectiles on normal strength concrete targets. Five projectiles were recovered using a soft recovery system to determine the average mass and nose shape of the projectiles. Velocity data for each test was measured with a high speed camera. The average projectile nose shape and mass plus the striking velocity, and the penetration depths from ten tests were compared to existing penetration equations to see if one or more of the equations is applicable for this type of projectile impact. The coarse aggregate gradation used in the concrete mix has Hugoniot data available. The Hugoniot data allows comparison of any observed spalling with the theoretical predictions.

Abstract. Foamed concrete as aerated concrete widely used in range of constructions application, no exception to structure shield. As structure shield is important to resist on impact loading. Whilst, Rice Husk Ash (RHA) as agro-waste potentials as filler for foamed concrete. RHA that is produced by uncontrolled burning under 700ºC during ± 6 hours obtain the granules contain the carbon and porous. The granules of RHA may fill the porous in matrix foamed concrete without remove the characteristic the foamed concrete its self as aerated concrete. This investigation RHA has been used as a replacement for fine aggregate. Target density 1800 kg/m 3 of foamed concrete both of with and without RHA have been produced to compare their strength and characteristic of impact resistance. SEM and EDS test has been conducted to determine microstructure and chemical composition of foamed concrete with RHA. The results showed that granules of RHA filled the porous and bonded with the denser part into matrix. The presence of granules of RHA has been changing the role of the air cell of porous in foamed concrete when it was subjected to impact loading. Also the granules of RHA give the foamed concrete denser without losing its characteristic of porous entirely.

“…The main problems facing the usage of reinforced concrete to resist impact loading that may cause penetration or perforation of slabs in buildings, shelters,….etc are much smallness in ductility of concrete slabs and needing of big slab thickness or great reinforcing steel ratio in slab section [1] H.D.
