Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

open access: yesphysica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

Cubic Lattice Rib Shape: Tuning of Poisson's Ratio and Cosserat Characteristic Length

open access: yesphysica status solidi (b), EarlyView.
Cubic rib lattices are studied in the context of effects of rib cross‐section shape on Poisson's ratio and on Cosserat characteristic length. It is possible to control Poisson's ratio over a wide range via appropriate rib cross‐section shape. Both Cosserat characteristic lengths can be made much larger than the cell size for torsion dominated rib ...

Negative Stiffness Induced and Controlled by Constriction

open access: yesphysica status solidi (b), EarlyView.
Structures with negative stiffness can be stabilized by constriction of external displacement. Furthermore, constriction can make a conventional positive stiffness material exhibit negative stiffness, either bidirectional or unidirectional (shown in the figure).

Physically consistent mesoscale model evaluation in complex terrain

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study introduces a novel approach for evaluating mesoscale atmospheric models in complex terrain by selecting physically consistent grid points and applying height‐based corrections. The method corrects for sensor height and terrain elevation differences between model and observations using a time‐varying lapse rate.

Assessing wildfire dynamics during a megafire in Portugal using the MesoNH/ForeFire coupled model

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Weather conditions affect megafires by inducing different fire behaviors over several days or weeks. The coupled MesoNH/ForeFire code was used to represent the dynamics of fire generating pyro‐convective clouds. To advance the understanding of wildfire dynamics, high‐resolution coupled fire–atmosphere modeling was employed.
