“…In finite-element simulation, a good model can not only ensure the accuracy of the simulation, but also save time. Different from traditional impact simulation [ 24 , 25 , 26 ], small balls of different sizes are used to simulate the micro-convex peaks and abrasive particles. Compared with the abrasive grains, the hardness of the micro-convex peaks is relatively soft.…”

“…Many researchers have already explored the STF-Kevlar composite materials through simulation. Sen et al [ 24 ] used CEL to explore the impact resistance of Kevlar-STF composites. The simulation results showed that the lateral deformation, energy distribution, etc., of the Kevlar-STF composite materials were significantly improved compared with the current multi-layer pure Kevlar.…”

Based on the clustering effect of shear-thickening fluids (STFs), a high-shear low-pressure flexible grinding wheel has been developed. In order to explore the material removal mechanism, the coupled Eulerian—Lagrangian (CEL) method is adopted to simulate the novel grinding process. The simulation results show that particle clustering effects do occur at the tangential and bottom positions of the micro-convex peak when it instantaneously strikes the workpiece surface. The particle clusters drive the harder abrasive particles to resist the strong interactions of micro-convex peaks. The micro-convex peaks are removed due to the cutting effect of the harder abrasive particles. Compared with traditional grinding, the ratio of tangential force to normal force for the high-shear low-pressure flexible grinding wheel is improved. The various trends in force ratio are consistent with the experimental results, which verifies the effectiveness of high-shear low-pressure grinding.

“…After impregnated with STF, the impact resistance to aramid fabric is significantly improved, because the presence of kaolin nanotube reduces the average travel of SiO 2 nanoparticles to form clusters, thus promoting shear thickening. 32 The existing research studies and applications of STF are mostly based on SiO 2 particles/PEG to prepare STF. However, when nano-SiO 2 is used as the dispersed phase, due to the large amount of hydroxyl on the surface of nano-SiO 2 , it is easy for nano-SiO 2 particles to aggregate through the hydroxyl hydrogen bond, thus reducing the dispersion of SiO 2 particles in the dispersed medium.…”

Shear thickening liquid (STF) is a new nonNewtonian fluid widely used in industrial production. In this paper, a novel shear thickening and dispersing system, namely poly methyl methacrylate (PMMA)/1-butyl-3-methylimidazole hexa-fluorophosphate ([BMIM]PF 6), was prepared using ultrasonic with PMMA as the dispersing phase and [BMIM]PF 6 as the dispersing medium. The stability, thixotropic, reversibility, rheology, and viscoelasticity of the dispersion system was studied, respectively. The dispersed system has good stability. The dispersed system shows high response sensitivity to shear rate, as well as good reversibility to shear thickening. Compared with traditional silicon dioxide/polyethylene glycol dispersion system, PMMA/[BMIM]PF 6 dispersion system displays a significantly enhanced shear thickening effect. Nonionic surfactant triton X-100 of 4 wt% can greatly improve PMMA/[BMIM]PF 6 dispersion system's shear thickening behavior. This paper provides a new idea for the further development of protective materials by using STF.

“…It was established that the application of shear thickening fluid (STF) on the woven fabrics could increase inter-yarn frictional force. [22][23][24][25][26] Other recent findings showed that the application of ZnO nanowires 27,28 and graphene oxide coating 29 on the fiber surface increases interyarn friction, and the resultant fabrics exhibit improved protection against impact. Nevertheless, there are some disadvantages related to the aforementioned chemical treatments.…”

This paper investigates the penetration and energy absorption mechanisms of ultra-high-molecular-weight polyethylene plain weaves with different fabric properties. Impact tests along with finite element (FE) analysis were used to study the impact response of the fabrics. In this research, the impacting projectile did not cause any fiber or yarn failure on the samples. It was found that structural parameters determine the yarn pull-out behavior and the softness of the resultant fabrics. Fabrics formed by loosely interlaced yarns tend to exhibit higher softness and less resistance against yarn pull-out. When the projectile velocity is not sufficient to initiate yarn pull-out, material softness determines the depth of the backface signature on the clay witness. This trend is more pronounced in a multi-ply fabric system than in a single-ply system; when yarn pull-out occurs, the projectile-slowing mechanism depends on the frictional force between the warp and weft yarns. Therefore, fabric softness becomes less important, and the yarn pull-out behavior of the fabric plays a predominant role in energy absorption. FE prediction showed that tightly woven fabrics exhibit a larger area of stress distribution and material deformation than those with severe yarn pull-out and, consequently, these tight fabrics tend to absorb more kinetic energy and sustain higher impact load from a projectile.
