Wave propagation in square granular crystals with spherical interstitial intruders.
TL;DR: Experiments and numerical simulations reveal that stiffer defects are more efficient at redistributing energy outside the impacted chain and soft defects induce a localization of the energy at the defect.

Effects of weak disorder on stress-wave anisotropy in centered square nonlinear granular crystals.
TL;DR: The effects of statistical variation in the particle diameters are investigated and the effects of the resulting disorder are compared in experiments and numerical simulations, finding good agreement.

Explosively generated pulse propagation through particles containing natural cracks
TL;DR: In this paper, an experimental study was conducted to study dynamic load transfer through particulate assemblies containing a damaged particle, where the authors focused on the influence of damage size and orientation on the group wave velocity, wave dispersion and peak contact load attenuation of the stress wave pulse.

Elastic waves through a packing of spheres
TL;DR: In this article, the elasticity of a hexagonal close packing of equal spheres is treated and the packing is anisotropic and because of the weight of the spheres, also inhomogeneous.

The effect of cementation on the elastic properties of granular material
Jack Dvorkin,Gary Mavko,Amos Nur +2 more
TL;DR: In this paper, a simple analytical model is developed to describe the mechanics of cemented granular material, and the two-dimensional problem of the deformation of an arbitrarily shaped cement layer has been reduced to an ordinary differential equation of the second order.
