“…The method of using measurements of phase during ringdown to extract nonlinear parameters from a continuous fitting function has, to our knowledge, not been previously employed. Previous time-domain analysis of acoustic nonlinearity has been performed with RF waveforms [13,14]. However, that analysis was performed with incremental fitting or incremental Fourier transformation of RF waveforms during ringdown, rather than fitting to a continuous function.…”

“…11. The change in the values of Q-factor from undamaged to damaged state has been previously used as a method to quantify damage (Eiras et al 2014). However, for nonlinear materials, the value of Q-factor depends on the acceleration (Chen et al 2011).…”

Elastic modulus measurements are often required to evaluate the structural performance or to estimate the damage in cement-based materials. The axisymmetric flexural vibration (AFV) of a thick circular disk is a test method that can be used to estimate the dynamic elastic modulus of cement-based materials. Cement-based materials are inherently nonlinear materials and their nonlinearity increases with damage. The main objectives of this paper are to investigate the consequences of material nonlinearity on the AFV measurements, and to understand the implications of the change of material nonlinearity with damage on these measurements. In this work, experimental measurements are performed on mortar specimens damaged by freeze-thaw. Acoustic emission is used as a benchmark method to monitor and quantify the damage.

“…The material nonlinearity was investigated using a short-time Fourier transform-based approach, to track frequency changes as the signal amplitude decays naturally, following the procedure proposed in Ref. 33. A sliding window containing 10 cycles moves through a single-time response signal and transforms the time segment within the window to the frequency domain at every window position.…”

“…The present paper evaluates the variation of the linear and nonlinear dynamic properties upon carbonation of mortar samples, using resonant vibration data obtained according to the standard ASTM C215-14. 22 Previous research conducted by the authors 33 showed how to extract and quantify the nonlinear behavior due to mechanical hysteresis using a standard test configuration setup (see Sec. 2.2).…”

Effect of carbonation on the linear and nonlinear dynamic properties of cement-based materials

Abstract. Carbonation causes a physicochemical alteration of cement-based materials, leading to a decrease of porosity and an increase of material hardness and strength. However, carbonation will decrease the pH of the internal pore water solution, which may depassivate the internal reinforcing steel, giving rise to structural durability concerns. Therefore, the proper selection of materials informed by parameters sensitive to the carbonation process is crucial to ensure the durability of concrete structures. The authors investigate the feasibility of using linear and nonlinear dynamic vibration response data to monitor the progression of the carbonation process in cement-based materials. Mortar samples with dimensions of 40 × 40 × 160 mm were subjected to an accelerated carbonation process through a carbonation chamber with 55% relative humidity and >95% of CO 2 atmosphere. The progress of carbonation in the material was monitored using data obtained with the test setup of the standard resonant frequency test (ASTM C215-14), from a pristine state until an almost fully carbonated state. Linear dynamic modulus, quality factor, and a material nonlinear response, evaluated through the upward resonant frequency shift during the signal ring-down, were investigated. The compressive strength and the depth of carbonation were also measured. Carbonation resulted in a modest increase in the dynamic modulus, but a substantive increase in the quality factor (inverse attenuation) and a decrease in the material nonlinearity parameter. The combined measurement of the vibration quality factor and nonlinear parameter shows potential as a sensitive measure of material changes brought about by carbonation.
