The Effect of Particle Strength on the Ballistic Resistance of Shear Thickening Fluids

open access: yes, 2013
The response of shear thickening fluids (STFs) under ballistic impact has received considerable attention due to its field-responsive nature. While efforts have primarily focused on the response of traditional ballistic fabrics impregnated with fluids ...

Coexistence of absolute negative mobility and anomalous diffusion [PDF]

open access: yes, 2019
Using extensive numerical studies we demonstrate that absolute negative mobility of a Brownian particle (i.e. the net motion into the direction opposite to a constant biasing force acting around zero bias) does coexist with anomalous diffusion.

Ballistic Impact Study of an Aramid Fabric by Changing the Projectile Trajectory

open access: yesFibers
Personal protective systems widely use aramid textile fabrics, whether in soft or rigid form, to protect against various types of ballistic threats. Ballistic impact refers to a high-velocity impact caused by a thrusting source, often involving a low ...

Design of the ballistic performance of shear thickening fluid (STF) impregnated Kevlar fabric via numerical simulation

open access: yesMaterials & Design, 2023
Shear thickening fluids (STFs) can effectively enhance the ballistic performance of Kevlar. Considering that the unique shear thickening effect of STF is the key factor to enhance the impact resistance of fabrics, this study sought to reveal the impact ...

Failure and impact behavior of facade panels made of glass fiber reinforced cement(GRC) [PDF]

open access: yes, 2011
GRC is a cementitious composite material made up of a cement mortar matrix and chopped glass fibers. Due to its outstanding mechanical properties, GRC has been widely used to produce cladding panels and some civil engineering elements.

Validation of the modified digital element approach for simulating ballistic impact against fragment simulating projectile

open access: yesMATEC Web of Conferences, 2018
A modified digital element approach (DEA) is applied to simulate fabric perforation process under ballistic impact. The previous version of the DEA is capable of simulating ballistic impact of textile fabric using rigid body spherical and cylindrical ...

Impact of particles on the Planck HFI detectors: Ground-based measurements and physical interpretation [PDF]

open access: yes, 2014
The Planck High Frequency Instrument (HFI) surveyed the sky continuously from August 2009 to January 2012. Its noise and sensitivity performance were excellent, but the rate of cosmic ray impacts on the HFI detectors was unexpectedly high.

Photoswitchable Conductive Metal–Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

Impact of loss on the wave dynamics in photonic waveguide lattices

open access: yes, 2014
We analyze the impact of loss in lattices of coupled optical waveguides and find that in such case, the hopping between adjacent waveguides is necessarily complex.
