Providing guidance and serving as a reference for ACFM instrument development, the text delves into visualization research in ACFM, offering valuable insights for technical engineering applications. Nondestructive testing (NDT) emerges as a pivotal method for detecting and assessing defects, offering support for safety pre-warning and maintenance decisions in industrial structures. Originating from the 1980s, the demand for an NDT technique arose to inspect fatigue cracks at welded intersections in offshore underwater structures in the North Sea. Conventional NDT methods proved impractical in this distinct underwater environment with quantitative evaluation requirements, prompting the development of the ACFM technique by researchers in the mechanical engineering department at University College London. Over the past four decades, ACFM's theory model, inspection methods, and equipment have undergone rapid advancements, gaining widespread utilization in ocean engineering, the power industry, rail traffic, and special equipment fields. This book encompasses diverse facets, including the global development history of alternating current field measurement technology, core basic theory, signal processing methods, probe instrument development, standardization construction, and engineering applications. Serving as a valuable learning reference for students and offering fundamental theoretical guidance for scientific researchers, it also provides case introductions for engineering applications. The book aims to propel both theoretical research and practical applications of alternating current field measurement technology, contributing significantly to its popularization and widespread application. 606 $aElectronics 606 $aPetrology 606 $aMechanical engineering 606 $aElectronics and Microelectronics, Instrumentation 606 $aPetrology 606 $aMechanical Engineering 615 0$aElectronics. 615 0$aPetrology. 615 0$aMechanical engineering. 615 14$aElectronics and Microelectronics, Instrumentation. 615 24$aPetrology. 615 24$aMechanical Engineering. 676 $a621.381 700 $aLi$b Wei$4aut$4http://id.loc.gov/vocabulary/relators/aut$0721674 702 $aYuan$b Xin'an$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aZhao$b Jianming$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aYin$b Xiaokang$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aLi$b Xiao$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910890900703321 996 $aAlternating Current Field Measurement Technique for Detection and Measurement of Cracks in Structures$94221521 997 $aUNINA
