The Viscoelastic Behaviour of Auxetic Metamaterials

physica status solidi (b), Volume 263, Issue 8, August 2026.
Stretch‐only auxetic unit‐cell viscoelastic models are extended from elastic honeycomb and keyway lattices using Maxwell and standard‐linear‐solid representations. Different horizontal and oblique relaxation responses make Poisson's ratio time‐ and frequency‐dependent, enabling tuneable auxetic behaviour for damping and adaptive structures.

Effect of Foam Faces and Butterfly Auxetic Core on Sandwich Nanoplate Vibration and Buckling

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT This research examines the thermomechanical vibration and buckling properties of a three‐layer sandwich nanoplate, which consists of foam face layers and a butterfly‐shaped auxetic core. The formulation is developed based on Hamilton's principle and higher‐order shear deformation theory (HSDT), utilizing an analytical Navier‐type solution to ...

3D Wave Dispersion Analysis of Sandwich Plates With GPRL‐Reinforced FGM Face Layers Containing Anti‐Tetrachiral Auxetic Metamaterials

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT In this study, the 3D wave dispersion properties of a metamaterial nanoplate with GPRL‐reinforced functionally graded material (FGM) surface layers were investigated using refined sinusoidal shear deformable plate theory (RSSDT) and nonlocal strain gradient theory (NSGT).

Generative Design of Energy‐Absorbing Auxetic Metamaterials via Variational‐Autoencoder Latent‐Space Exploration and Nonlinear Finite‐Element Screening

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT Auxetic cellular structures, which exhibit a negative Poisson's ratio, are conventionally designed manually, one topology at a time. This paper presents a generative design framework in which a convolutional variational autoencoder (VAE) with a low computational cost, trained on 31,920 solid isotropic material with penalisation (SIMP ...

Multi‐Scale Spatial Variations in Pacific Mantle Seismic Anisotropy: Constraints on Plate Evolution and Asthenospheric Flow

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract We present array‐scale (∼500 × 500 km) anisotropic shear‐velocity models from two Pacific ocean‐bottom seismometer (OBS) arrays of the OBS Research in the Convecting Asthenosphere (ORCA) experiment: Young ORCA (∼43 Ma) and Old ORCA (∼90 Ma). Rayleigh‐wave phase velocities spanning 5–150 s are combined with Love‐wave phase velocities from 5 to ...

Large Amplitude Free Vibration of thick Laminated Composite Plates with Magnetorheological Core Via a New Sinusoidal Shear Deformation Theory

Large amplitude free vibrations have nonlinear behavior that may be detrimental to structures . As a result, they need to be effectively regulated .A composite sandwich panel with a magnetorheological (MR) core's nonlinear vibration was examined, and the softening and hardening behaviors were investigated utilizing the New Sinusoidal Shear Deformation ...

A Physics‐Based Frequency‐Temperature Seismic Anelastic Attenuation Model for Planetary Ice Shells

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Intrinsic attenuation in planetary ices remains poorly constrained at seismic frequencies and low temperatures, limiting quantitative predictions of wave propagation in icy moons. Existing models typically rely on constant‐Q, or power‐law formulations that lack microphysical grounding and fail to capture the strong temperature sensitivity of ...

A Novel Framework for Understanding Multiaxial Fatigue of SBR Through Monitored Tension‐Torsion Tests

Strain, Volume 62, Issue 4, August 2026.
A new methodology shows that current multiaxiall fatigue criteria are not sufficient. ABSTRACT In the present work, mappings of two invariants of the true strain tensor, K2$$ {K}_2 $$ that measures the magnitude of the distortion and K3$$ {K}_3 $$ that quantifies the mode of distortion, are used to investigate the multiaxial fatigue of AE2 and AE42 ...
