Analysis of impact chattering [PDF]

open access: yesMiskolc Mathematical Notes, 2017
In this paper, mechanical models with Newton's Law of impacts are studied. One of the most interesting properties in some of these models is chattering. This phenomenon is understood as the appearance of an infinite number of impacts occurring in a finite time.
