ABSTRACT
We found differing characteristics in the backscattered signal depending on the presence of light and heavy impurities in a granular chain. The difference is due to soliton confinement in the region of the light impurity of the granular medium, while there is no such phenomenon for the case of a heavy impurity. This difference may be used to discriminate nondestructively between light and heavy impurities in the granular medium.

We review recent developments on the topic of impulse propagation in assemblies of elastic beads, where the beads interact upon contact via the (nonlinear) Hertz potential. The role of solitary waves in granular systems is emphasized. The effects of impurities, disorder and restitution are...

Wave propagation in dilatant granular materials is studied by using a hierarchical Korteweg-de Vries type evolution equation. The model equation is solved numerically under harmonic initial conditions. The behaviour of the solution is described and analysed over a wide range of material...

Plane Cosserat solids are introduced. It is shown that only one parameter is needed to describe intrinsic rotation. The field equations are simple enough to study the propagation of nonlinear waves and can be reduced to some particular form that admits different nonlinear waves, including...

We study the dynamic response of one- dimensional granular chains composed of uniform hollow spheres excited by an impulse, and we observe the formation and propagation of highly nonlinear solitary waves. We find that the dynamics of these solitary waves are different from the solitary waves...

Any impulse results in the formation of a solitary wave of time averaged width $$W$$ in a granular chain. If the grain-grain interaction potential $$V\sim \delta ^n$$, where $$\delta$$ is the distance by which the grains approach each other, then it is well established that $$n\ge 2$$. Here we...

We consider a simple problem that of a horizontal alignment of identical grains, and insure that the grains are in gentle mutual contact and held between two rigid fixed end walls. Grain-grain interactions are intrinsically nonlinear according to the Hertz law and hence no sound waves can...

Wave propagation in microstructured media is simulated numerically making use of two different models. In the first case a Kortewegâ€“de Vries type equation is used for modeling 1D wave motion in granular materials. In the second case a Boussinesq type equation is applied for modeling 1D...

We study the dynamic response of uniform granular chains composed of short cylindrical particles excited by an impulse. The particles in the chains are arranged with their axes orthogonal to the chain's axis, and the particles maintain a constant relative orientation angle. We study the...
