Stress functions for elastodynamics in consideration of viscous damping.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1985 This paper deals with an extension of a method of solution in terms of stress function for dynamic problems of elasticity to the case of an elastic solid with viscous damping. It is Assumed that the damping forces considered in this paper are proportional to the velocity of motion of particles in a solid, and Hooke's law for stresses an strains holds ...

Nanopore‐Based Protein Deceleration and Sensing Using Graphene/Si3N4 Dual Membrane Cavity
Advanced Science, EarlyView.A graphene/Si3N4 dual membrane cavity system achieves multi‐stage protein deceleration through spatial geometry. Multi‐level current traces provide high‐resolution spatial localization and early warning signals. ABSTRACT Sequencing of protein with nanopores has emerged as a powerful tool offering rapid readout, high accuracy, low cost, and portability.

A generalized framework for viscous and non-viscous damping models
The inadequacy of the classical viscous damping model in capturing dissipation across a wide range of applications has led to the development of non-viscous damping models. While non-viscous models describe damping force satisfactorily, they offer limited physical insight.

VISCOUS DAMPING MODEL FOR LATERALLY OSCILLATING MICROSTRUCTURES
, 1994 Viscous energy loss in oscillating fluid-film dampers that provide frictional shear for laterally-driven planar microstructures is investigated. It is found that Stokes-type fluid motion models viscous damping more accurately than Couette-type flow field.

Dissipation mechanisms identification of soft hollow particle-dampers in honeycomb structures for micro-vibrations environment [PDF]
, 2009 Particle dampers are enclosures partially filled with metallic or glass small spheres, attached to the vibrating structure. This paper deals with replacing hard classical particles by soft hollow ones to maximize damping and mass ratio. Hence, one aspect

Chemically Programmable Underwater Sound‐Absorbing Metamaterial via MXene Self‐Assembly
Advanced Science, EarlyView.MXene self‐assembly creates a chemically programmable underwater metamaterial with quasi‐periodic layers and a chemical‐physical multi‐level constraint system. A crosslinker as a ‘chemical scissor’ precisely edits microscopic interactions, exciting deep‐subwavelength strong local resonances that induce near‐zero/negative effective bulk modulus (Keff ...

A Study of Viscous Air Damping in Laterally Oscillating Micro Comb Structures
, 2013 This paper studies analytically as well as numerically viscous air damping in laterally oscillating micro comb structures. The analytical results demonstrate that the transient motion is damped out in less than one oscillating period of the comb ...
