Measurements and Simulations of Wave Propagation in Agitated Granular Beds
2004
AIP Conference Proceedings
Wave propagation in a granular bed is a complicated, highly nonlinear phenomenon. Yet studies of wave propagation provide important information on the characteristics of these materials. Fundamental nonlinearities of the bed include those in the particle contact model and the fact that there exists zero applied force when grains are out of contact. The experimental work of Liu and Nagel showed the strong dependence of wave propagation on the forming and breaking of particle chains. As a result
