Shear horizontal (SH) waves are of great importance in structural health monitoring (SHM)
and nondestructive testing (NDT), since the lowest order SH wave in isotropic plates is non …

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 …

The guided Lamb wave is widely acknowledged as one of the most encouraging tools for
quantitative identification of damage in composite structures, and relevant research has …

In order for composite materials to be used more extensively in load carrying aircraft
structures, they have to be maintained in a safe and economical manner. Critical flaws may …

The interaction of individual Lamb waves with a variety of defects simulated by notches is
investigated using finite-element analysis, and the results are checked experimentally …

The detection of corrosion in insulated pipes is of major importance to the oil and chemical
industries. Current methods involving point-by-point inspection are expensive because of …

This review paper focuses on interdigital electrodes-a geometric structure encountered in a
wide variety of sensor and transducer designs. Physical and chemical principles behind the …

Guided acoustic and ultrasonic waves have been utilized in various manners for non-
destructive evaluation and testing. If a guided wave mode is dispersive, a pulse of energy …

Structural health monitoring (SHM) using guided waves is one of the only ways in which
damage anywhere in a structure can be detected using a sparse array of permanently …

The inspection of large structures using conventional ultrasonic bulk wave techniques is
slow because scanning is required if the whole structure is to be tested. Ultrasonic guided …
