**Preface to "Interfacial Dissipative Phenomena in Tribomechanical Systems"**

In the last twenty years, tribology and non-linear dynamics have reached major milestones in describing rough contact, friction, damping mechanisms, and dynamical behavior of non-linear systems, which are paving the way for the future engineering technologies. The two fields are largely intertwined as, among the others, contact non-linearities are almost omnipresent in any technical application ranging from the development of NEMS/MEMS to bioengineering, automotive, civil/mechanical industry, and aerospace.

The common thread in both fields is the study of interfaces, particularly of the dissipative phenomena that take place at the interface, providing the source of damping that is exploited to reduce the vibration amplitude of mechanical systems, improving their service life. Despite the great achievements obtained, we are still far from being able to predict the dynamical behavior of mechanical systems involving contact interfaces. Contamination of knowledge between tribology and non-linear dynamics is of outmost importance today to develop strategies to respond promptly to future challenges.

The current Special Issue aimed at bringing together, in the same Issue, contributions from world-leading scientists working in the fields of tribology and non-linear dynamics, with the aim to favor "contamination" of knowledge from the two fields of research.
