In many weakly nonlinear dispersive systems, like water waves, optics, plasma physics, etc., the relevance of solitons, modulation instability and breathers is widely accepted and still a matter of intense research. In vibrations comparatively little work seems to have been devoted to investigate system behaviour along these lines. The presentations will show first results obtained from simple model systems for which solitons, modulation instability and breathers have been generated. The potential role of these solutions for studying questions related to spatio-temporal localisation, extreme events, and irregular vibration is discussed.
