Ballistic Impact on Ceramic/aramid Armour Systems
The ballistic performance of the lightweight armour systems was examined to obtain an estimate for the V50 and the global damage of the composite plates. All estimates were performed by varying the thickness of ceramic tiles, while maintaining equal areal density of the system. Simulation predictions and trial results is demonstrated both in terms of deformation and damage of the laminates and ...
متن کاملIs behind armour blunt trauma a real threat to users of body armour? A systematic review.
INTRODUCTION Behind armour blunt trauma (BABT) has been defined as a non-penetrating injury caused by the rapid deformation of body armour. There has been an increasing awareness of BABT as an injury mechanism in both the military and civilian worlds; whether BABT results in serious injuries is debatable. METHOD A systematic review of the openly accessible literature was conducted using the P...
متن کاملExperimental and numerical analysis of stress wave propagation in polymers and the role of interfaces in armour systems
Advanced polymeric materials are finding an increasing range of industrial and defence applications. These materials have the potential to improve combat survivability, whilst reducing the cost and weight of armour systems. In this paper the results from a split Hopkinson pressure bar (SHPB) test of a high density polyethylene (HDPE) sample involving multiple stress waves is discussed with aid ...
متن کاملRationing in health systems: A critical review
Background: It is difficult to provide health care services to all those in need of such services due to limited resources and unlimited demands. Thus, priority setting and rationing have to be applied. This study aimed at critically examining the concept of rationing in health sector and identifying its purposes, influencing factors, mechanisms, and outcomes. Methods: The c...
