Abstract
Practical techniques for experimentally detecting and characterizing system nonlinearities are demonstrated through a test bed consisting of a composite panel, both with and without a disbond, undergoing an electrodynamic shaker excitation. Techniques for detecting and characterizing system nonlinearities are applied to force and response data collected from this test bed, and then models are identified for those nonlinearities. Both time and frequency domain techniques are utilized, and the underlying theory and experimental requirements for each technique are discussed. References to the literature are provided throughout the chapter for more in-depth discussion of the techniques.
