Force attenuation performance in sandwich structures with STF and M-STF encapsulation

Heliyon
In this study, we investigate the role of adding shear thickening fluids (STFs) and multi-functional shear thickening fluids (M-STFs) to the core of a sandwich-structured composite made of aluminum facesheets and XPS foam cores with different geometries on force attenuation performance.

Shear thickening fluid (STF) in engineering applications and the potential of cork in STF-based composites

Advances in Colloid and Interface Science
Shear thickening fluids (STFs) are a unique type of fluids that can quickly transform into a solid-like state when subjected to forces (rate dependent). These fluids are created by dispersing micro and nanoparticles within a medium. When the force is removed, they return to their original liquid state.

Study of mechanical property of shear thickening fluid (STF) for soft body-armor

Materials Research Express, 2021
STFs have been widely used for soft body-armor because of STF reversible and repeatable thickening characteristics. However, shear thickening mechanism characterized by rheological properties cannot well explain thickening mechanism of STF against the ...

Entre o “faça o que eu digo” e o “faça o que eu faço”: uma análise da coerência entre o ensinado e o decidido pelos Ministros do STF

Revista de Investigações Constitucionais, 2022
Este artigo objetivou discutir se haveria ou não coerência entre o que os Ministros do STF ensinam em suas doutrinas e aquilo que eles decidem em casos difíceis enquanto juízes constitucionais, considerando as polêmicas levantadas pelo paradigma ...
