Abstract
Nonlinear acoustic methods have shown potential for the identification of early damage in brittle materials such

as concrete. Commonly, these methods evaluate relative nonlinearity parameters from multiple resonance tests at

different amplitudes. We demonstrate a recently developed alternative method, Impact Nonlinear Reverberation

Spectroscopy (INRS), where quantitative nonlinearity parameters are evaluated from a single impact resonance

test. The recorded reverberation of the measured signal is matched to a synthetic nonlinear damped signal. The

proposed model allows instantaneous true physical amplitude, frequency, and damping of each mode to be

characterized as a function of time,... (More)

hysteretic material nonlinearity can be quantitatively characterized over a notably wider dynamic range compared

to conventional methods. Two examples from the application to concrete and stabilized soil are presented. (Less)
