Chattering: an overlooked peculiarity of rocking motion

AI Giouvanidis, EG Dimitrakopoulos, PB Lourenço - Nonlinear Dynamics, 2022 - Springer
Complete chattering occurs when a structure undergoes a theoretically infinite sequence of
impacts in finite time, that eventually bring the structure to the state of persistent (continuous) …
