Toughness and edge-toughness

open access: yesDiscrete 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 \(\omega (G-S)\geq 2\).

Numerical simulation on 90° impact test of aluminium alloy wheel with the effect of tyre

open access: yesScientific Reports
Car wheels are crucial to automobile safety, requiring a rigorous test before production. A 90° impact test simulates the frontal impact and its influences on the wheel structure, replicating dynamic driving conditions.
