Sound attenuation and anharmonic damping in solids with correlated disorder [PDF]
Condensed Matter Physics, 2010 We study via self-consistent Born approximation a model for sound waves in a disordered environment, in which the local fluctuations of the shear modulus G are spatially correlated with a certain correlation length The theory predicts an enhancement of the density of states over Debye's omega(2) law (boson peak) whose intensity increases for increasing

Cicada Wing-Inspired Skeleton-GO Networks in Melamine Foams for Multifunctional High-Performance Composites. [PDF]
Adv Sci (Weinh)Inspired by the intricate microstructure of cicada wings, researchers developed a novel in situ skeleton‐graphene membrane architecture within lightweight foams. This bioinspired design dramatically enhances multifunctional performance: vibration attenuation time decreases by ∼83.3%, damping capacity increases by ∼179.3%, and compressive modulus rises ...

Sound attenuation in high mach number oscillating bubble media
Ultrasonics Sonochemistry, 2023 We study theoretically and numerically sound attenuation in bubble-containing media when the bubbles are freely oscillating at high Mach numbers. This paper expands one of the main forms of bubble-related acoustic damping factors by extending the ...

An Energy-Balancing Perspective of Interconnection and Damping Assignment Control of Nonlinear Systems [PDF]
, 2003 Stabilization of nonlinear feedback passive systems is achieved assigning a storage function with a minimum at the desired equilibrium. For physical systems a natural candidate storage function is the difference between the stored and the supplied ...
