To explain the mechanics of perforation of thick metallic target plates a modified version of the analysis suggested by Awerbuch and Bodner [2] is given by a cylindrical projectile. Although the analysis retains the basic concept of the perforation process to occur in three stages as was assumed by Awerbuch and Bodner [2] a new explanation, as to the cause and effect of the compressive force is...

Since the introduction of the term “wound ballistics”[1,2] indicating the study of the wounding mechanisms of missiles [3], extensive experimental research on this field has beenconductedby investigators with a military background [4-7]. In the context of wound ballistics, the term missile is used to denote various types of small projectiles, such as bullets and fragments, that have enough kine...

The use of high-speed puncture mechanics for prey capture has been documented across a wide range of organisms, including vertebrates, arthropods, molluscs and cnidarians. These examples span four phyla and seven orders of magnitude difference in size. The commonality of these puncture systems offers an opportunity to explore how organisms at different scales and with different materials, morph...

A ballistic projectile launching device was used to study the penetration behaviors of tungsten alloy spherical fragments various diameters into carbon fiber composite target plates different thicknesses. Based on test results, we obtained relationship between ultimate velocity, plate thickness, and fragment diameter as well energy incident velocity. Using dimensional analysis, a formula relati...

The scope of this paper is to investigate the performance ultra-high fiber reinforced concrete (UHPFRC) slabs, under projectile impact. Mixture impact loading was examined using bullets with 7.62 mm diameter and initial velocity 800 m/s. UHPFRC, used in study, consists a combination steel fibers two lengths: 6 13 same 0.16 mm. Six composition mixtures were tested, four one (UHPC), without fiber...
