Wave tailoring granular materials: effect of randomness and plane wave propagation
… as practical significance of impact response in granular media. In the first part of the study, we investigate numerically the effect of randomness in material and geometric properties on wave propagation behavior in 1D and 2D granular media. Results obtained for both 1D chains and 2D media show …

Experimental study of the development of plastic solitary waves in one-dimensional granular media
… bar (SHPB) is used to impact one-dimensional granular chain of spheres. These homogeneous chains used here comprise of brass, aluminum, or stainless steel spherical beads, ranging from a single sphere to a chain of fourteen, and are of interest because of their unique wave propagation …

Compactons in strongly nonlinear lattices
… example in which compactons can be found is the granular chain. In the third part, we study systems which are related to the discrete nonlinear Schrödinger equation describing, for example, coupled optical wave-guides or the dynamics of Bose-Einstein condensates in optical lattices. Our …

Wave propagation in one dimensional confined granular media
Ordered granular media, such as a one dimensional aligned chain of spherical particles, have unique dynamic properties arising from the contact interaction of their individual grain constituents. A primary result of this contact, the formation of solitary waves in dynamically loaded one dimensional …

Theoretical and experimental studies of the dynamics and acoustics of forced ordered granular networks
Ordered arrays of granular particles (beads) have attracted considerable attention in recent years due to their rich dynamical behaviors and interesting properties. Depending on the ratio of static to dynamic deformations between particles the dynamics of granular media is highly tunable ranging …

Numerical simulations of dense granular systems with and without cohesive effects
Granular materials are collections of objects ranging from sand grains that form sand piles or even sand castles to collections of large objects such as a group of meteors in outer space. The considered range of sizes of granular particles is such that the effect of thermal fluctuations is not …
