A simple imaging method for non-destructive evaluation

2010 URSI International Symposium on Electromagnetic Theory, 2010
This paper presents an inverse scattering method for imaging defects embedded into known structures based on a modified version of the linear sampling method. The main features of the proposed approach are the computational effectiveness paired with a non-approximated modeling. As such, the method is able to deliver reliable results almost in real time.

Non-destructive evaluation of glass corrosion states

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1998
Abstract Ion beam based composition analysis of silicate materials can be strongly affected by natural surface corrosion. The simultaneous application of Proton Induced X-ray Emission (PIXE) and Proton Induced Gamma-ray Emission (PIGE) proves useful to distinguish between thin or extended leached surface areas on glasses.

Modeling for quantitative non-destructive evaluation

Ultrasonics, 2002
A quantitative approach to non-destructive evaluation (NDE) must be based on models of the measurement processes. A model's purpose is to predict, from first principles, the measurement system's response to material properties and anomalies in a material or structure. For the ultrasonic case a measurement model should include modeling of the generation,

Non destructive evaluation in the time domain

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 1999
In this paper a method is presented for an efficient solution of the direct problem (find the scattered field for a given thin crack and driving field) in the time domain. This is a fundamental step in any non destructive evaluation problem. Two different approaches, one in the time domain and the other based on Fourier analysis, are used and compared ...

Non-destructive evaluation techniques

Anti-Corrosion Manual, 1982
This article is a condensation of the author's work that first appeared in “Dimensions” Nov. 1980, the magazine of the National Bureau of Standards, U.S. Dept. of Commerce. With non-destructive testing techniques playing an increasing role in corrosion monitoring, it is published here as it is felt that it gives a succinct introduction to NDT which ...
