Multiple ballistic impacts of thin metallic plates: Numerical simulation
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2022The ballistic performance of protective structures under multiple projectile impacts attracts increasing attention due to its practical importance, and existing studies were seldomly devoted to exploring how the structure would deform and fail when subjected to such loads.

Finite Element Simulation of Ballistic Impact in Survivability Studies
45th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics & Materials Conference, 2004*† The analysis of a projectile impacting an object at high velocity is of great importance to the survivability community. The probability of a kill given a hit for a component is based upon projectile mass and velocity. Therefore the mass and velocity at impact, as well as the residual mass and velocity after impact, must be known.

Computational simulation of fabric armour subjected to ballistic impacts
International Journal of Impact Engineering, 2006In computational simulations of ballistic impacts on woven polymeric fabric armour, specialized fabric models are normally used. Attempts have also been made to use commercial finite element packages for such purposes. However, such attempts normally result in either overly simplified models or prohibitively detailed finite element discretization of ...

Numerical simulation of composite armor subjected to ballistic impact
Materials Today: Proceedings, 2019Abstract Composite materials are widely used in the engineering field due to their high strength-to-weight ratio which offers enhanced mechanical behaviour of the components. Some of the widely used fields for the composite materials are body armors, safety shoes, sports and in many other regions.

Ballistic impact of a KEVLAR® helmet: Experiment and simulations
International Journal of Impact Engineering, 2008Helmet designs have evolved over the last three millennia and the use of helmet may be as old as warfare itself. In 600 B.C. the Greeks in Sparta crafted single-piece helmet from bronze, which provided complete head protection, leaving only narrow slits in front for vision and for ventilation. Later in 250 B.C.

Finite element simulation of ceramic/composite armor under ballistic impact
Composites Part B: Engineering, 2011Abstract In this paper, based on LS-Dyna code, a new finite element (FE) simulation of the ballistic perforation of the ceramic/composite targets, which impacted by cylindrical tungsten projectiles, has been presented. Research on this method has been conducted by a few research groups in recent years.

Ballistic impact of fibre composite armours by fragment-simulating projectiles
Composites Part A: Applied Science and Manufacturing, 1996Abstract Tests have been conducted in which 1.1 g fragment-simulating projectiles (FSPs) were fired at nylon 6,6/ ethylene vinyl acetate composite laminates. The laminates were manufactured at two pressing loads and two values of areal density (mass per unit area).

Numerical simulation of ceramic composite armor subjected to ballistic impact
Composites Part B: Engineering, 2010Abstract Armor systems made of ceramic and composite materials are widely used in ballistic applications to defeat armor piercing (AP) projectiles. Both the designers and users of body armor face interesting choices – how best to balance the competing requirements posed by weight, thickness and cost of the armor package for a particular threat level.

Oblique Ballistic Impact Simulation of Flexible Body Armors Under Viscous Friction
2020 Advances in Science and Engineering Technology International Conferences (ASET), 2020The projectiles have included RCC and spherical shapes, and viscoelastic interactions and slip between the both the projectiles and the target and between the target layers and fabric yarns have been modeled. Besides exploring new phenomena, these models have been useful for validating previous analytical models where various simplifying assumptions ...
