Detection of a 15 % crack in a 10 mm thick plate made of aluminum and a 20 % crack in a 20 mm thick plate has been confirmed. In this paper we present theoretical analysis
The conductive nature of aluminum makes electromagnetic non-destructive testing methods a common means of detecting cracks in aluminum plates. Eddy current
Transient eddy currents generated by probe designs that utilize the ferrous fastener as a flux conduit have demonstrated the capability of detecting subsurface cracks at depth within

Aluminum and titanium testing standards pictured along with an eddy current sensor. The aluminum testing standard has three cracks with depths of 8, 20, and 40 mil, while
The inspection and location of cracks adjacent to aluminum fastener holes is of great interest to the aircraft industry. Due to skin effect reasons, conventional eddy current
These cracks on thinner bottom skin layers can be obscured by thicker top plates with paint. A portable GMR (Giant Magnetoresistive) sensor-based eddy current system
This paper presents numerical modeling and experimental measurements of eddy current (EC) probe for detecting subsurface defects in 10 mm to 15 mm thick conducting specimen.
Cutting thick plates is affected not only by the laser power but also by the cut kerf width and the melt flow dynamics that determine the ejection of the molten material.
