nondestructive high-sensitivity detections of metallic

Intelligent detection of cracks in metallic surfaces using a

Crack detection using microwave sensors is typically based on human observation of change in the sensor's signal (pattern) depicted on a high-resolution screen of the test equipment. However, as demonstrated in this work, implementing artificial intelligence to classify cracked from non-cracked surfaces has appreciable impact in terms of sensing sensitivity, cost, and automation.

Ultrasonic inspection provides a sensitive method of nondestructive testing in most materials, metallic, nonmetallic, magnetic or nonmagnetic. It permits the detection of small flaws with only single surface accessibility and is capable of estimating location size of the defect Providing both surfaces are parallel, ultrasonics may be used for thickness measurement, where only one surface is

Giant magnetoresistance based eddy current probes for

Detection of deeply buried cracks and of small cracks initiating at edges of metallic parts and structures are among the challenges encountered by the nondestructive testing industry. Solid-state magnetic sensors based on Giant Magneto-Resistance (GMR) and Spin-Dependent Tunneling (SDT) effects have been integrated in eddy current probes that are capable of addressing these difficult problems

Among these, EC-based techniques seem the most promising because of their low cost and high sensitivity, although they are only applicable to conductive structures. The EC techniques are based on the analysis of the magnetic field perturbation due to eddy currents induced in the material under test.

Nondestructive Evaluation Physics : Waves

Sensitivity is the ability to locate small discontinuities. Sensitivity generally increases with higher frequency (shorter wavelengths). Resolution is the ability of the system to locate discontinuities that are close together and tell them apart within the material or located near the part surface.
