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

Optimal determination of the elastic constants of composite materials from ultrasonic wave‐speed measurements
TL;DR: In this article, the elastic constants of anisotropic solids from wave-speeds measurements in arbitrary non-principal planes are determined by minimizing a functional derived from a nonlinear system of equations.
Journal ArticleDOI
Combined laser spot imaging thermography and ultrasonic measurements for crack detection
TL;DR: In this article, the authors used both cw and pulsed laser beam illumination on stainless steel and titanium samples and the technique was found to be successful for determining the location of fatigue cracks, where a surface crack, close to a small, well defined heated spot, impedes lateral heat flow and produces alterations in the shape of the thermal spot image that can be monitored by thermography.
Journal ArticleDOI
Material characterization of functionally graded material by means of elastic waves and a progressive-learning neural network
TL;DR: In this paper, a procedure is suggested for characterizing the material properties of functionally graded material (FGM) plate by using a modified hybrid numerical method (HNM) and a neural network (NN).
Journal ArticleDOI
Microstructure and mechanical properties of titanium components fabricated by a new powder injection molding technique
TL;DR: A powder injection molding (PIM) binder system has been developed for reactive metals such as titanium that employs an aromatic compound as the primary component to facilitate easy binder removal and mitigate problems with carbon contamination.
Journal ArticleDOI
Thermographic detection of surface breaking defects using a scanning laser source
TL;DR: In this paper, surface breaking defects are detected using a scanning laser source to deposit heat into a sample surface, and any lateral flow of heat is disturbed by such a defect, with a change in thermal spot shape being detected by an infrared camera.

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.
