Numerical analysis of ballistic impact performance of two ceramic-based armor structures

open access: yesComposites Part C: Open Access, 2020
This paper investigates ballistic performance of two different ceramic-based armor designs using finite element analysis. The first design is a bi-layer armor consists of a ceramic front layer and a Kevlar-29 composite backing layer.

Research on ballistic performance of green shear thickening functionalized fabric based on solid waste modification

open access: yesMaterials & Design
Based on the solid waste-based modification, green shear-thickening functionalized ballistic composites were prepared. Silica aerosols were obtained from solid waste diatomaceous earth through sol–gel preparation, gel aging, and supercritical drying. The

Experimental and numerical study on CuO/ZnO-modified aramid fabric for ballistic and UV radiation protection

open access: yesPolymer Testing
Aramid fabrics are widely used in bulletproof armor because of their excellent mechanical properties. Previous studies have shown that ultraviolet radiation has a negative effect on the mechanical properties of aramid yarn, so improving the mechanical ...

Effect of ballistic exercise program on shoulder dynamic stability, throwing performance and shoulder strength among university level female cricket bowlers

open access: yesBangabandhu Sheikh Mujib Medical University Journal
Background: Bowling in cricket is a ballistic movement requiring rapid force generation. The Thrower's Ten and Ballistic Six programs are widely used for overhead athletes to enhance shoulder performance. Unlike general ballistic exercises, the Ballistic
