Proximity to Jamming Governs Acoustic Attenuation in Damped Packings
Colton Kawamura, Derek R. Olson, Anthony P. Austin +3
We use particle-based numerical simulations to address a longstanding question regarding the origins of the linear frequency dependence of attenuation in fluid-saturated granular m…

An explicit granular-mechanics approach to marine sediment acoustics
Abram H. Clark, Derek R. Olson, Andrew J. Swartz +1
Here we theoretically and computationally study the frequency dependence of phase speed and attenuation for marine sediments from the perspective of granular mechanics. We leverage…
