Modeling for quantitative non-destructive evaluation
Ultrasonics, 2002A 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 of glass corrosion states
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1998Abstract 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.

Non-destructive testing (NDT) methods are employed in the technical field as a precautionary to avoid accidence or emergency situations for the human and the environment. A risk situation in the technical field could happen if the load of a component is increasing and the wall thickness due to defect growth is decreasing until a critical defect ...

The current chapter introduces a wide range of non-destructive evaluation (NDE) inspection techniques currently used for the assessment of structures. Such techniques may be broadly classed as either passive or active. In the current work, techniques are considered passive if no additional stimulus or excitation is added to the structure or component ...

Non Destructive Evaluation of Ceramics
1994Currently more attention is being paid to the non destructive test facilities for ceramics and to improve the resolution of the techniques. In this review the applicability of microfocus radiography, ultrasonics, scanning laser acoustic microscopy, thermo acoustic imaging, scanning photo displacement microscopy, acoustic emission, dye penetrants and ...

Electromagnetic Non-Destructive Evaluation of Reinforced Concrete Rebars
2008This paper concerns quantitative imaging, consisting in finding location, direction and size, of concrete rebars by means of eddy current measurements and an innovative inversion method. Owing to an accurate numerical modelling of the probe-rebar interaction, an analysis of issues to be considered for the quantitative imaging of rebars is conducted ...

Ultrasonic caustics in non-destructive evaluation
Journal of Physics D: Applied Physics, 1980Caustics formed in the field diffracted by defects are explored theoretically as a possible approach to the inverse scattering problem for ultrasonic non-destructive evaluation. The case of crack-like defects is considered in detail using the geometrical theory of diffraction. The involute of the far-field caustic reproduces the projection of the crack
