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

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)
