“…Formed damage, such as a crack in structures, could accumulate debris over time and accelerate structure deterioration, paving the way for catastrophic failure. The accumulated debris causes crack closure, affects crack propagation and enhances pitting corrosion activities, as explained in [5,6]. The prime effects of corrosion and crack on metallic structures are thickness thinning, rigidity reduction, integrity and load-carrying-capacity degradation [7], shortening the structure's service lifecycle and making it unreliable.…”

Continuous monitoring of structural health is essential for the timely detection of damage and avoidance of structural failure. Guided-wave ultrasonic testing (GWUT) assesses structural damages by correlating its sensitive features with the damage parameter of interest. However, few or no studies have been performed on the detection and influence of debris-filled damage on GWUT under environmental conditions. This paper used the pitch–catch technique of GWUT, signal cross-correlation, statistical root mean square (RMS) and root mean square deviation (RMSD) to study the combined influence of varying debris-filled damage percentages and temperatures on damage detection. Through experimental result analysis, a predictive model with an R2 of about 78% and RMSE values of about 7.5×10−5 was established. When validated, the model proved effective, with a comparable relative error of less than 10%.

“…Structural damage that causes thickness variation has been associated with corrosion activities [2]. The initiation of corrosion activities in different ways is revealed in [3]. Early damage detection is necessitated due to the severe implications of damage to structures, especially during service time.…”

“…Damage filled with substances could be dominantly found in static structures. Substances in this study are referred to as debris or fluid [3]. Empty damage is formed when a crack, dent or notch is devoid of filled substances, while filled damage is formed when the damage traps and accumulates debris or fluid that could close it.…”

“…Empty damage is formed when a crack, dent or notch is devoid of filled substances, while filled damage is formed when the damage traps and accumulates debris or fluid that could close it. The filled damage has the potential for pitting corrosion formation over time [3]. Pitting corrosion is a localized damage with various depths and irregular geometry.…”

Human health monitoring (HHM) is essential for continued daily task execution, as is structural health monitoring (SHM) for structures to ensure the continual performance of their designed tasks with optimal efficiency. The existence of damage in a structure affects its optimal use through stiffness deterioration. Damage of different forms could occur in a structure but have the singular objective of material degradation, leading to its underuse for a task. Guided wave ultrasonics has shown strength in detecting sundry damage in structures, but most of the damage monitored and detected is unfilled with substances. However, some damage could trap and accumulate substances that could hasten material degradation through corrosion activities under favorable conditions, especially in the oil and gas industry. This study used the ultrasonic-guided waves’ pitch–catch inspection technique to identify damage filled with different materials. The assessment was based on the RMSD of the dominant Lamb wave mode’s average maximum amplitude and the response signals’ transmission coefficient (TC). A five-cycle tone burst of excitation signals of different frequencies was created to generate propagating Lamb waves in the structure. The fundamental antisymmetric mode was found to be more sensitive than the fundamental symmetric mode when detecting damage filled with various substances. At 80 kHz, the deviation of the current response signals from the baseline response signals due to different filled substances in the damage was distinct and decreased with increased fluid viscosity. Given that structures in the oil and gas sector are particularly susceptible to substance-induced damage, the outcomes of this study are paramount.
