Summary: Nowadays, nonlinear vibration methods are increasingly used for detecting damage mechanisms in anisotropic and heterogeneous polymer matrix composite (PMC) materials. This study employed two nonlinear vibration methods, nonlinear resonance (NLR) and single frequency excitation (SFE), to detect different types of damage in PMC using an in situ embedded polyvinylidene fluoride (PVDF) piezoelectric sensor. The effectiveness of the integrated PVDF sensor was validated using an accelerometer.

Summary: In this study, conformable shear mode ultrasonic transducers made of flexible piezoelectric PLLA fibers were designed and evaluated for underwater structural health monitoring applications. The transducers exhibited consistent sensitivity in detecting defects in both liquid and air. The shear mode in PLLA fibers, which originates from the crystal structure, does not require electrical poling and is resistant to aging.

Summary: This paper proposes a new method with high accuracy for evaluating corrosion condition using EMI method and PZT sensors in concrete structures. Experimental results show that PZT sensors are sensitive to compressive force, and comparison between specimen behavior and EMI measurements can be used for corrosion detection. Based on the findings, a solution for detecting corrosion rate, direction, and initiation period is proposed.

Summary: This paper investigates the Lamb wave based structural health monitoring for aluminum bolted joints with multiple-site fatigue damages through experiments. Multiple fatigue cracks were observed at different bolt holes during the fatigue testing. The damage index (DI) was compared before and after the initiation of the fatigue cracks, but it was found to be overestimated due to phase shifts. To overcome this, the envelope damage index (EDI) that considers the envelope curves of the signals was introduced and proved to be a better parameter for monitoring the fatigue crack size and location.
