Y. HURMUZLU (Mech. Eng. Depart., University of Dallas)

Titre : "Using the Impulse transmission ratio in solving multiple impact problems".

Résumé :  In this talk, I present the definition of the Impulse Transmission Ratio and its application to solve three classical, multi-impact problems :

1) One dimensional chain of spherical particles (Newton's cradle)

2) Two dimensional particle chains

3) The rocking block.

                         I conclude the talk by outlining an approach (co-developped with Stronge) that may gap the bridge between the rigid body and compliance based methods of solving collision problems.
