TLDR
The Review of Progress in Quantitative NDE (ROPQN) as mentioned in this paper is the world's leading conference in reporting annually new research and development results in quantitative NDE and promotes communication between the research and engineering communities and emphasize current reporting of work in progress.Abstract:
The Review of Progress in Quantitative NDE is the world's leading conference in reporting annually new research and development results in quantitative NDE. The conference reports on both fundamental and applied advances in NDE and promotes communication between the research and engineering communities and emphasize current reporting of work in progress. Attendees include representatives of academia (including students), industry, and government with approximately one-half coming from the United States and the other half from overseas. This volume represents the best report of ongoing work that is available anywhere. Connections and overlap with the medical diagnostic community are highlighted.read more

On the measurement of anisotropic elastic constants of fiber-reinforced composite plate using ultrasonic bulk wave and laser generated Lamb wave
Tsung-Tsong Wu,Y.-H. Liu +1 more
TL;DR: In this article, a hybrid elastic wave method was developed to determine the anisotropic constants of a thin fiber-reinforced composite plate based on the measurements of the pure mode bulk ultrasonic wave velocities as well as the Lamb wave velocity.
Journal ArticleDOI
Ultrasonic method to determine gas porosity in aluminum alloy castings: Theory and experiment
TL;DR: In this article, the porosity in solids using the frequency dependence of the ultrasonic attenuation is discussed both from the theoretical and experimental viewpoint, and the major thrust of the work is the determination of the volume fraction and size of the voids for the case of dilute porosity (<6%).
Journal ArticleDOI
Progress in scanning probe microscopy
TL;DR: In this paper, the development of the key concepts of scanning probe microscopes is reviewed from their early history to current technologies, and some key applications of scanning probes are presented and future advances that are likely to come to fruition in the next decade are discussed.
Journal ArticleDOI
Non-contact, automated surface wave measurements for the mechanical characterisation of concrete
TL;DR: In this paper, two automated devices for conducting non-contact ultrasonic measurements (with air coupling and laser interferometry) for the purpose of recovering mechanical properties (porosity) on a series of concrete slabs using surface waves.

A model relating ultrasonic scattering measurements through liquid–solid interfaces to unbounded medium scattering amplitudes
R. B. Thompson,T. A. Gray +1 more
TL;DR: In this article, the relationship between scattering data obtained from ultrasonic experiments, in which the waves are excited and detected in a finite measurement geometry, and unbounded medium, farfield scattering amplitudes is considered.

Scattering matrix for elastic waves. III. Application to spheroids
TL;DR: Using the scattering matrix approach to elastic wave scattering, numerical results are presented for the scattering of P and S waves from prolate and oblate spheroidal cavities and inclusions embedded in an elastic solid for a wide range of wavelengths as discussed by the authors.
