Abstract Penetrating trauma by energised fragments is the most common injury from an explosive event. Fragment penetrations to truncal region can result in lethal haemorrhage. Personal armour used mitigate ballistic threats; it comprises hard protect high-velocity bullets and soft against other threats (such as a hand gun) with low impact velocities. Current testing standards for do not focus o...

The “Poems of Doubtful Authorship” in modern editions Samuel Johnson’s poetry include three Latin poems that were first associated with Johnson 1856. This article reveals the weakness this alleged “attribution” and discusses arguments for against authorship each poem turn. While certainty is impossible, it concludes he possibly wrote translation Ex cantico Solomonis but Venus Armour Logical War...

Aetosaurs are a group of quadrupedal, armoured pseudosuchian archosaurs from the Upper Triassic. They are characterized by dorsal and ventral carapaces, and appendicular osteoderms, all of them ornamented. Aetosaurs have been proposed as index fossils largely based on the distinctiveness of some osteoderms. Therefore, it is important to understand the intraspecific variation of these elements i...

It is well known that yaw can affect the penetrative power of armour piercing rounds. To investigate this effect purely experimentally is difficult because the typical ballistic set up does not allow control over the yaw angle of the projectile. In this study, a numerical model is used complementing ballistic experiments for a range of yaw angles. For the projectile, a validated computer model ...

It is important to understand how ballistic materials respond impact from projectiles such that informed decisions can be made in the design process of protective armour systems. Ballistic testing a standards-based where are tested determine whether they meet protection, safety and performance criteria. For V50 test, fired at different velocities key parameter known as limit velocity (BLV), abo...
