Computational Study of Breathing-type Processes in Driven, Confined, Granular Alignments

Abstract

The study concerns the dynamics of granular alignments held between rigid walls when the systems are subjected to continuous, large, forces at one end. It turns out that under such dynamical loading, granular chains exhibit peculiar quasi-periodic behavior. A deeper understanding of the physics associated with such behavior could lead to the development of multifaceted frequency sensors and energy harvesting technologies. The work also led to a deeper understanding of the contact forces between elastic grains with non-elliptic contact interfaces. In the course of the three years (2008-2011), this grant allowed us to support the work of two PhD students and one undergraduate who did an undergraduate honors thesis.
