Analysis of restitution in rocking of single rigid blocks

A single rigid prismatic block is analysed for free rocking behaviour without slipping and jumping. A numerical procedure based on a precise contact detection is developed and tested. An extensive experimental study of free rocking for blocks of different slenderness and size is conducted, with the emphasis on the post-impact behaviour and energy-loss mechanism in the existing impact models. The experiments conducted strongly support the definition of the restitution coefficient proposed by Kalliontzis et al. A method is proposed to determine the extra parameter present in this model.
