RISElectric Field Analysis of Simultaneous Evaluation of Crack on an Inner Pipe Surface and Pipe Wall Thickness Using Direct-Current Potential Difference Method of Multiple-Probe Type
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The direct-current potential difference method (DC-PDM) is a promising nondestructive technique for evaluating cracks in the conductors on the basis of change in current paths or the potential ...
