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 nondestructive assessment of the damage that occurs in components during service
plays a key role for condition monitoring and residual life estimation of in-service …

Updated, revised, and restructured to reflect the latest advances in science and applications,
the fourth edition of this best-selling industry and research reference covers the fundamental …

A similarity may be found between various approaches for determining the effects of parallel
fractures or aligned cracks on seismic wave propagation at wavelengths that are long …

Ultrasonic waves reflected from the front and back surfaces of a thin layer are often not
separated in the time domain, and interfere. The spectrum of the resulting interference signal …

This paper concerns a study of the detectability of dry contact kissing bonds in adhesive
joints using three ultrasonic inspection techniques. Conventional normal incidence …

One approach to testing the suitability of an adhesive joint for a particular application is to
build and test to destruction a representative sample of the joint. In this way the best …

This paper presents a study of the detectability of kissing bonds in adhesive joints using an
ultrasonic inspection technique to measure nonlinearity. Kissing bonds are defined as …

Using a theoretical approach and computer simulations, we calculate the normal stiffness
and the transverse stiffness of the interface between two contacting isotropic solids with …

In this work, it is suggested that a unique set of the interfacial stiffness constants, KN and KT,
is sufficient to characterize the macroscopic elastic response of an interface between two …
