Detection of early-stage corrosion on slender steel members is crucial for preventing buckling failures of steel structures. An active photoacoustic fiber optic sensor (FOS) system is reported herein for the early-stage steel corrosion detection of steel plates and rebars using surface ultrasonic waves. The objective of this study is to investigate a potential method for detecting surface corrosion/rust of steel rods using numerically simulated surface ultrasonic waves. The finite element method (FEM) was applied in the simulation of propagating ultrasonic waves on steel rod models. The pitch-catch mode of damage detection was adopted, in which one source (transmitter) and one sensor (receiver) were considered. In this research, radial displacements at the receiver were simulated and analyzed by short-time Fourier transform (STFT) for detecting, locating, and quantifying surface rust located between the transmitter and the receiver. From our time domain and frequency domain analyses, it was found that the presence, location, and dimensions (length, width, and depth) of surface rust can be estimated by ultrasonic wave propagation.

“…In the past, FEM had been applied for simulating ultrasonic wave propagation for damage detection [14][15][16]. Among various signal processing techniques, short-time Fourier transform (STFT) has been demonstrated as an applicable approach for analyzing the transient response of ultrasonic wave propagation in the time-frequency domain [17].…”

Detection of early stage corrosion on slender steel members is crucial for preventing 1 buckling failures of steel structures. An active photoacoustic fiber optic sensors (FOS) system 2 has been reported for early stage steel corrosion detection of steel plates and rebars using surface 3 ultrasonic waves. The objective of this paper is to investigate the surface corrosion/rust detection 4 problem on steel rods using numerically simulated surface ultrasonic waves. The finite element 5 method (FEM) is applied in simulating the propagation of ultrasonic waves on steel rod models. 6Transmission mode of damage detection is adopted, in which one source (transmitter) and one sensor 7 (receiver) are considered. In this research, radial displacements at the receiver were simulated and 8 analyzed by short-time Fourier transform (STFT) for detecting, locating, and quantifying a surface 9 rust located between the transmitter and the receiver. From our time domain and frequency domain 10 analyses, it is found that the presence, location, and dimensions (length, width, and depth) of surface 11 rust can be estimated by ultrasonic waves propagating through the surface rust.

“…They are constantly optimized and upgraded in different industries, and their computational accuracy has made a breakthrough. For example, a finite-element method (FEM) was adopted to quantify the early-stage corrosion of rebars inside reinforced concrete [29]. Yaman et al [30] also employed the FEM to simulate the stress wave propagation of a heterogeneous concrete model composed of mortar and aggregate and verified its feasibility.…”

Although nondestructive ultrasonic technologies have been applied in laboratory and field tests in the field of heritage conservation, few studies have quantified the relationship among the real microstructures, micromechanical properties, and macroscopic acoustic responses of earthen-site soils. This paper develops a micromechanics-based multiscale model for quantitatively exploring the ultrasonic propagation characteristics of elastic waves in untreated and consolidated earthen-site soils. Scanning electron microscope images and image processing technology are integrated into the finite-element simulation. The effects of microstructure and wave features on the acoustic characteristics of soils are quantitatively investigated under pulsive loading. The simulation results of untreated and consolidated soils are efficiently compared to ultrasonic test data. It is demonstrated that the integration of microstructure image processing and multiscale modeling can predict the ultrasonic pulse velocity well, which improves the accuracy of laboratory testing and field monitoring and better serves the evaluation and implementation of engineering practice in the field of heritage conservation.
