Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

Ballistic performance of hybrid composite structures

open access: yes, 2021
The aim of this study is to numerically investigate the ballistic behavior of composites with different thicknesses and different reinforcements. The guns were shot at four different velocities on composite models using armor-piercing 7.62 M61 AP projectiles.

Influence of Hornification Treatment and Fiber Length on the Performance of Recycled Polypropylene Composites

open access: yesPolymer Composites, EarlyView.
Study of the influence of hornification treatment and jute and mallow fiber length on the physical, thermal, and mechanical properties of recycled polypropylene (PP) composites. ABSTRACT The growing accumulation of plastic waste has driven its reuse in the development of new composites, with natural fibers emerging as promising reinforcements. However,

Effects of Different Projectile Nose Shapes on the Impact Performance of the Aluminium 2024 Thin Plate

open access: yesPolytechnic Journal
In this study, the impact performance of the Al2024 thin plate target was determined through a numerical approach. Two different-nosed hard steel projectiles, including a blunt and a sphere, were used in order to obtain the ballistic impact of the target.

Comparative Assessment of Energetic Plasticizers Including NFPEG3N3 in a GAP/HMX Formulation: Mechanics, Stability, Combustion, and Performance

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We examine the new energetic plasticizer 3‐(2‐(2‐(2‐azidoethoxy)ethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG3N3), three reference compounds (BDNPA/F, Bu‐NENA, and DNDA‐57), and a plasticizer‐free control in a fixed HMX/GAP composite. NFPEG3N3 provides the strongest low‐temperature properties, yielding the lowest formulation glass transition ...
