A mathematical model of critical jet heights causing droplets splashing in BOF steelmaking
Metalurgija, 2022 It is important to understand the physical interaction between top-blown oxygen jet and liquid bath in basic oxygen steelmaking furnaces (BOF). In this study, cold model experiments were carried out to investigate the cavity depth, diameter and the ...

Weak Bonds in a Biomimetic Adhesive Enhance Toughness and Performance.
Journal of the American Chemical Society, 2020 Developing future high performance adhesives is predicated upon achieving properties including strength and ductility. However, designing tough materials that are simultaneously strong and soft is usually contradictory in nature.

Stretchable materials of high toughness and low hysteresis
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Many applications in engineering require stretchable materials that dissipate little energy during normal operation of cyclic loads (low hysteresis), but dissipate much energy to resist rupture (high toughness), and survive prolonged cyclic ...

Discrete Mathematics, 1997 The toughness of a graph \(G\), introduced by \textit{V. Chvátal} [Discrete Math. 5, 215-228 (1973; Zbl 0256.05122)] in studying hamiltonicity, is the largest real number \(t\) for which \(|S|\geq t\omega (G-S)\) for every \(S\subseteq V(G)\) with \(\omega (G-S)\geq 2\).

Commentary on using H/E and H/E as proxies for fracture toughness of hard coatings
Thin Solid Films, 2019 While positive correlation between fracture toughness and H/E and H3/E2 has been reported for some ceramic coatings, we outline an argument that such correlation cannot be true in general, especially for nanolayer and nanocomposite coatings that present ...
