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

A review of non-destructive techniques for the detection of creep damage in power plant steels
TL;DR: A critical review of the main results obtained to date in the secondary and tertiary stages of creep is presented in this article, and the advantages and disadvantages of each method are discussed.
Journal ArticleDOI
Guided wave health monitoring of complex structures by sparse array systems: Influence of temperature changes on performance
TL;DR: This paper investigates how a temperature compensation method can be used to reduce the number of signals required in the database, and the strong influence of signal complexity and mode purity on the effectiveness of this method is shown.
Journal ArticleDOI
Substructural organization, dislocation plasticity and harmonic generation in cyclically stressed wavy slip metals
TL;DR: In this paper, a non-Hookean stress-strain relationship is quantified by a material nonlinearity parameter β that for a given fatigue state is highly sensitive to the volume fractions of veins and persistent slip bands (PSBs), PSB internal stresses, dislocation multipole configurations, dislocations loop lengths, dipole heights and the densities of secondary dislocations in the substructures.

Two‐dimensional surface dopant profiling in silicon using scanning Kelvin probe microscopy
Albert K. Henning,Todd Hochwitz,James A. Slinkman,James M. Never,Steven Hoffmann,Phil Kaszuba,Charles Daghlian +6 more
TL;DR: In this article, a simultaneous combination of scanning Kelvin probe microscopy and scanning atomic force microscopy has been applied to the problem of profiling dopant concentrations in two dimensions in silicon microstructures.
Journal ArticleDOI
Three-dimensional imaging system based on Fourier transform synthetic aperture focusing technique
TL;DR: In this paper, the Fourier transform synthetic aperture focusing technique is used to yield a quantitative 3D image of defects residing in the homogeneous and isotropic bulk material. And the implementation of this algorithm into an ultrasonic imaging system is described, which mainly comprises an array processor and high-resolution graphics to display the three-dimensional reconstruction volume as a walk-through along three orthogonal planes.

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.
