The early work on long range guided wave nondestructive testing (NDT) was largely done in
industry, and multiple applications were developed before a surge in academic interest …

Ultrasonic feature guided waves (FGW) have been found to exist in a variety of topographic
waveguides, such as welds, bends and stiffeners in plate-like structures. These FGWs are …

In our previous research, the second harmonic generation (SHG) of feature guided waves
(FGWs) in a welded joint with material nonlinearity was analyzed theoretically and observed …

Engineering structures are often composed of thin elements containing features such as free
edges, welds, ribs, and holes, which makes distant safety inspections based on guided …

Abstract Resistance Seam Welding (RSW) is frequently used in many industries where low-
cost mass manufacturing of gas/fluid-tight seals are required. One particular use case is in …

Extensional edge waves propagate along the edges of plates, with low attenuation in the
propagation direction and amplitude decreasing rapidly (within one or two wavelengths) in …

Detecting near-edge damage in composite structural elements using guided wave-based
techniques can be challenging, primarily due to the complexity of wave analysis arising from …

Guided waves (GWs) based damage detection techniques are vital for ensuring structural
safety and are extensively applied in aerospace, mechanical, and civil engineering due to …

Structural integrity of nuclear assets and their associated infrastructure is key to national
security, energy generation, and efficient deployment of capital. Furthermore, building …
