Concept of Short-Range Radar and Counter-Projectile for Detecting and Countering Armour-Piercing Projectiles [PDF]

open access: yesProblemy Mechatroniki, 2021
During warfare and acts of terrorism an extreme threat to vehicles and other high-value assets comes from armour-piercing projectiles. Under these conditions, defence systems should include devices capable of rapid detection of these threats.

Visual Methods to Assess Strain Fields in Armour Materials Subjected to Dynamic Deformation—A Review

open access: yesApplied Sciences, 2020
When impacted by a projectile, ballistic protection undergoes very large strain rates over very short periods of time. During these impact events, materials will undergo a very short region of elastic deformation, before undergoing significant plastic ...

Complexity evaluation for the implementation of a pre-FFT equalizer in an OFDM receiver [PDF]

open access: yes, 2000
A pre-FFT equalizer (PFE) has been shown to offer a significant throughput efficiency improvement when applied to an OFDM receiver. Alternatively, the PFE can be used to increase the maximum delay spread conditions under which the OFDM system can operate

Damage Evolution Prediction during 2D Scale-Model Tests of a Rubble-Mound Breakwater: A Case Study of Ericeira’s Breakwater

open access: yesModelling, 2022
Melby presents a formula to predict damage evolution in rubble-mound breakwaters whose armour layer is made of rock, based on the erosion measured in scale-model tests and the characteristics of the incident sea waves in such tests. However, this formula

Wounding patterns and human performance in knife attacks: optimising the protection provided by knife-resistant body armour [PDF]

open access: yes, 2003
Stab attacks generate high loads,1 and to defeat them, armour needs to be of a certain thickness and stiffness.2,3 Slash attacks produce much lower loads and armour designed to defeat them can be far lighter and more flexible.Methods and subjects: Phase

On the Origin of Armour-marking in the German-speaking Lands [PDF]

open access: yesИсторическое оружиеведение, 2020
Master mark is one of the main basics for the correct attribution of the European armour. However, on studying the armour suits, manufactured before the second half of the 15th century, scholars are inevitably faced with the problem that no country ...

Flexible Modular Armour for Protection Against the 5.56 x 45 mm SS109 Projectiles [PDF]

open access: yesProblemy Mechatroniki, 2015
The paper presents the results of the depth of penetration tests (DOP) and numerical simulations of the 5.56 x 45 mm SS109 projectile impact onto passive, layered armours placed on the armour backing material.

Some early medieval swords in the Wallace Collection and elsewhere

open access: yesGladius, 2003
El análisis de ocho espadas altomedievales muestra que algunas de ellas fueron hechas a partir de una sola pieza de acero, mientras que a otras se les ha soldado un cortante filo de este material.
