Abstract: Whenever contact occurs, part of the mechanical energy is radiated as acoustic energy, inducing vibrations in the mechanical system with varying levels of intensity. The resulting dynamic response arises from a complex interaction across different spatial and temporal scales, leading to a wide range of frictional and vibrational behaviours.
Starting from a general overview of the characteristic time and length scales involved in the problem, different frictional scenarios will be discussed, with a particular focus on the onset of macroscopic stick-slip and to the interface dynamics governing the overall contact response.
Bio: Francesco Massi is currently Full Professor at the Department of Mechanical and Aerospace Engineering of Sapienza University of Rome. Between 2007 and 2012, he held the position of Lecturer at LaMCoS, INSA Lyon. He has been Visiting Professor at the Tribology Research Institute of Southwest Jiaotong University, the Laboratoire de Neurosciences Cognitives at Aix-Marseille Université, and the LaMcube laboratory at Centrale Lille.
He is a member of the Steering Committee of the Italian Association of Tribology and serves on the Editorial Boards of several international journals in the field of tribology. He has coordinated several research projects on both fundamental and applied topics. His research activities focus on tribology, dynamics, and biomechanics.
