Phys. Rev. E 68, 041304 (2003) [13 pages]Pulse dynamics in a chain of granules with frictionReceived 2 July 2003; published 15 October 2003 We study the dynamics of a pulse in a chain of granules with friction. We present theories for chains of cylindrical granules (Hertz potential with exponent n=2) and of granules with other geometries (n>2). Our results are supported via numerical simulations for cylindrical and for spherical granules (n=5/2). © 2003 The American Physical Society URL:
