On the “authentic damping mechanism” of the phonon damping model

Physical Review C, 2003
Some general features of the phonon damping model are presented. It is concluded that the fits performed within this model have no physical content.

New AI‐Assisted Approach for Expanding the Solution Space: Application to Lattice Structure Design

Advanced Engineering Materials, EarlyView.
This work introduces an innovative framework for designing structured materials by ex panding the design space through reparameterization of qualitative variables into continuous structural descriptors. Combined with machine‐learning‐based prediction and multi‐objective optimization, the approach enables the discovery of novel lattice architectures ...

The experimental response of a broadband base-excited vibration isolator incorporating cubic damping

, 2013
Structural damping is often assumed to be viscous and linear which leads to comparatively straightforward vibration analysis. In the case of vibration isolation mounts this assumption of linearity is particularly questionable and one might want to know ...

Non-Fermi-liquid behavior and anomalous suppression of Landau damping in layered metals close to ferromagnetism [PDF]

, 2015
Financial support from the EPSRC (U.K.) under Grants No. EP/G03673X/1 (S. P. R.) and No. EP/I031014/1 (C. A. H.) is acknowledged.We analyze the low-energy physics of nearly ferromagnetic metals in two spatial dimensions using the functional ...

Zero/low overshoot conditions based on maximally‐flatness for PID‐type controller design for uncertain systems with time‐delay or zeros

IET Control Theory & Applications
This paper extends the characteristic ratio approach using novel inequalities to ensure zero/low overshoot for linear‐time‐invariant systems with zeros.

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

Advanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

Numerical design and test on an assembled structure of a bolted joint with viscoelastic damping [PDF]

, 2015
Mechanical assemblies are subjected to many dynamic loads and modifications are often needed to achieve acceptable vibration levels. While modifications on mass and stiffness are well mastered, damping modifications are still considered difficult to ...
