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

Three-Dimensional Ultrasonic Crack Detection in Anisotropic Materials
TL;DR: In this paper, the scattering of probe-generated ultrasonic fields incident upon a strip-like crack in an anisotropic half-space is discussed, and an electric signal response is calculated via an electromechanical reciprocity relation.

Experimental Investigation of Mode Conversions of the T(0,1) Mode Guided Wave Propagating in an Elbow Pipe
TL;DR: In this paper, a method for a preferential detection of the torsional modes was proposed on the basis of the circumferential wave structures of the modes, which was utilized for investigations of mode conversions.

Miniaturized capacitive transducer for detection of broadband ultrasonic displacement signals
TL;DR: In this paper, a miniaturized version of the capacitive transducer for the detection of broadband, ultrasonic displacement signals at the surface of a specimen is described, which is especially well suited for measurements on a laboratory specimen which requires several of them to study an acoustic emission source, to characterize an elastic (or a viscoelastic) behavior of the material, or simply to...

Delamination detection in composite structures using laser vibrometer measurement of Lamb waves
TL;DR: In this article, the feasibility of using a scanning laser vibrometer for detecting hidden delamination in multi-layer composite composites is explored, where Lamb waves are excited by Lead Zirconate Titanate transducers mounted on the surface of a composite plate.

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.
