We investigate the effect of dynamic and uniaxial static loading on the wave speeds and rise
times of laser generated acoustic waves traveling through a disordered, multilayer …

Dynamic simulations of wave propagation are performed in dense granular media with a
narrow polydisperse size-distribution and a linear contact-force law. A small perturbation is …

Experiments on isotropic compression of a granular assembly of spheres show that the
shear and bulk moduli vary with the confining pressure faster than the 1∕ 3 power law …

Granular materials exhibit numerous rich and complex behaviours, which have been
investigated from both continuum and particulate perspectives. In particular, sound …

Contact-based vibrations play an essential role in the dynamics of granular materials.
Significant insights into vibrational granular dynamics have previously been obtained with …

We investigate elasto-plastic wave propagation in ordered two-dimensional granular media
consisting of contacting metallic granules. A Hopkinson bar generates a high-amplitude …

Granular materials are inherently heterogeneous, leading to challenges in formulating
accurate models of sound propagation. In order to quantify acoustic responses in space and …

We study the interaction of surface acoustic waves (SAWs) with a contact-based vibrational
resonance of 1 μ m silica microspheres forming a two-dimensional granular crystal adhered …

We study numerically the propagation of an acoustic pulse through a loaded granular
material under the hypothesis that the conventional modeling of solid friction used in soft …

For short duration impulse loadings, elastic granular chains are known to support solitary
waves, while elastoplastic chains have recently been shown to exhibit two force decay …
