A strongly nonlinear system often has multiple solutions under harmonic excitation.
However, measuring all of these multiple responses in structural dynamics is challenging …

A major difficulty when modelling nonlinear structures from experimental vibration data is to
determine the type of nonlinear functions that will better predict their dynamic response. In …

Global correlation analysis is an important technique to quantify both the shape and
amplitude differences between two response vectors. In linear dynamic systems, differences …
