Abstract
A perspective of the mechanisms by which energy is transferred from hi gh- to low-frequency modes is presented The focus is on some recent ex periments that reveal how a low-amplitude high-frequency excitation ca n produce a large-amplitude low-frequency response. Such a phenomenon is potentially harmful, if not catastrophic. Specifically, these exper iments clarify the role of internal resonances, combination external a nd parametric resonances, and the interactions among modes of widely s paced frequencies.
