Abstract
The LZB model introduced in the foregoing chapter, is first analyzed in terms of the post-impact velocity domain when its parameters (stiffness ratio, elasticity coefficient, balls masses, energetical restitution coefficients) are varied. Then it is validated through comparisons with experimental data found in the literature. Particular attention is paid to its capabilities to predict the wave effects in various types of chains (monodisperse, tappered, stepped, decorated), when dissipation is present or not. Further validations on column of beads falling on a rigid ground under the action of gravity, a bouncing dimer and a rocking block systems (which both involve multiple impacts with Coulomb’s friction) have been reported elsewhere and are not presented here.
