Electrical and Magnetic Methods of Non-destructive Testing

This revised and updated edition covers electrical and magnetic methods of non-destructive testing. The requirements for such testing are debated along with the criteria for the choice of a given method. This is followed by a summary of the general theory relating to electrical and magnetic testing techniques and a discussion of specific methods. Topics covered include: recent developments in magnetic methods of testing, such as SQUID magnetometry and Barkhausen emission testing; developments in eddy current testing such as improvements in probe design, the use of neural networks and defect imaging, especially with the use of magneto-optic method (MOI); and RADAR and potential drop methods of testing, especially of concrete structures. This volume should be of interest to engineers, scientists or postgraduates working in this field.
