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 ...

Numerical Simulation of Ballistic Impact on Different Types of Helmets
31st International Symposium on Ballistics, 2019The paper deals with numerical simulation of the response of the three types of helmets (combat helmets, helmets for military policeman and helmet for the paratroopers) to ballistic impact by the fragment simulating projectile (1.1 g). All tested helmets were made from aramid laminate.

Apollo 12 Lunar Module Impact: Laboratory Simulation and Possible Downrange Ballistic Effects
Science, 1970Plastic pellets were fired into sand targets at a launch angle of 4 degrees and a velocity of 1.68 kilometers per second, the conditions of the Apollo 12 lunar module impact. Shallow elliptical or doublet craters were formed, similar to certain lunar craters.

Three-Dimensional Modelling and Simulation of Ballistic Impact
2001Abstract : The overarching theme of the work originally proposed concerned the development of three-dimensional computational capability enabling the lagrangian simulation of armor penetration. The principal objectives of the work, as stated in the proposal, were: (1) The development of three-dimensional computational capability including adaptive ...

Polymer Composites
Fiber metal laminates (FMLs), which are constructed from thin metal sheets interspersed with fiber‐reinforced epoxy, are the focus of this study. Specifically, GLARE 2/1, which features a layer of glass fiber‐reinforced polymer (GFRP) sandwiched between ...

Simulation of ballistic impact on fabric armour using finite-element method
Journal of the Textile Institute, 2009This study presents an analytical model to calculate the residual velocity of projectile-penetrating targets composed of planar plain-woven fabric. A non-linear, explicit, three-dimensional finite-element code in ABAQUS 6.4 software is used to simulate the response of plain-woven fabric under high-speed projectile impact.

A Simple Analytical Model to Simulate Textile Fabric Ballistic Impact Behavior
Textile Research Journal, 1997Composite materials have become very attractive as personal and vehicle armors because of their light weight and high performance. Unfortunately, these materials are difficult to simulate numerically or analytically, and the only way to check their performance is experimentally.

Ballistic impact on fired clay masonry bricks
, 2020We perform an experimental and numerical study of ballistic impact on the German fired clay brick material VMz28. Parameters for the concrete material model applied in hydrocode simulations stem from material characterization experiments, especially ...
