TL;DR: The model developed provides not only very good agreement with existing data available in the open literature from experimental, density functional theory (DFT) and molecular dynamics simulations, but also highlights the specific deformation mechanisms existing in boron nitride sheets, and their difference with carbon-based graphitic systems.

TL;DR: In this article, a vibroacoustics analysis of auxetic gradient honeycomb composite structures with hexagonal configurations is presented, where two classes of gradient cellular layout are examined: one with continuously varying internal cell angle, the other with gradient cell wall aspect ratio across the surface of the honeycomb panel.

TL;DR: In this article, a 2D gradient auxetic core was used to optimize the vibrational properties of a hexagonal auxetic sandwich plate with a homogenized finite element model.

TL;DR: In this paper, the vibroacoustic behavior of anti-tetrachiral and auxetic hexagonal gradient sandwich panels using homogenized finite element models is described and first-order and random optimization methods are used for the minimization of radiated sound power level of the structures.

TL;DR: In this article, the temperature-dependent transverse mechanical properties of single-walled nanotubes were studied using a molecular mechanics approach, and the stretching and bond angle force constants describing the mechanical behaviour of the sp^{2} bonds were resolved in the temperature range between 0 K and 1600 K, allowing to identify a temperature dependence of the nanotube wall thickness.
