COMPLEMENTARY ELECTROMAGNETIC NON-DESTRUCTIVE EVALUATION
AIP Conference Proceedings, 2011The use of non‐destructive evaluation (NDE) for defect detection and failure prediction in structures and specimens is widespread in energy industries, aimed at ageing power plants and pipelines, material degradation, fatigue and radiation damage, etc. At present there are no suitable electromagnetic NDE methods for the measurement and characterization

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 ...

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 ...

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 ...

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
