• An impact oscillator is the term used here to represent a system which is periodically driven in some way and which also undergoes intermittent or a continuous sequence of contacts with motion limiting constraints. This important class of non-smooth dynamical systems not only exhibits typical characteristics of smooth nonlinear systems, such as generic bifurcations, multiple solutions and chaos, but also displays new phenomena. Additionally, many physical situations of practical engineering relevance have limits incorporated in their dynamic response and therefore impacts cannot be avoided. Engineers must evaluate the dangers associated with these impacts to eliminate excessive loads, reduce wear, avoid fatigue and in some cases increase passenger comfort. A full understanding of the underlying mathematics increases our ability to account for and control impacts. Vibrating beams, moored ships, rattling gears, and bouncing objects are all typical examples which have motivated studies. This theme issue contains a collection of papers which gives a background to the subject and highlights the mathematical peculiarities of systems with impact. Theory, numerics and experimental models are used to understand behaviour and give insight into the uses of these advances in engineering.
