Transient Electromagnetic-Thermal Nondestructive Testing: Pulsed Eddy Current and Transient Eddy Current Thermography

By Yunze He, Ali Sophian, Bin Gao

Transient Electromagnetic-Thermal Nondestructive Testing focuses on two cutting-edge techniques used for Nondestructive Testing (NDT): Pulsed Eddy Current (PEC) and Transient Eddy Current Thermography (TECT). These two electromagnetic nondestructive (EM NDT) techniques are a means to lower operation and maintenance costs and improve reliability and availability. Their advantages of high speed, high penetration, high sensitivity, wide spectrum, low cost, and easy quantification mean that they play an increasingly important role in: aerospace, renewable energy, marine science, railway, traffic control, civil engineering, and other industrial fields. Coverage includes, Theory: including the examination of multiphysics fields for (a) defect evaluation, such as parallel cracks, deep defects beneath the skin and (b) quantification, such as the analysis of thermal wave propagation for phase-based defect quantification, Methods: including a variety of EM-thermal NDT techniques; time-domain, frequency-domain, and logarithm-domain defect evaluation methods; advanced algorithms, such as principal components analysis (PCA), independent components analysis (ICA), support vector machine (SVM), Blind Source Separation (BSS) and multidimensional tensor decomposition; and image reconstruction and enhancement for improving detectability, Applications: including an analysis and evaluation of the variation In the properties of material including conductivity, permeability, and lift-off; experimental studies for real damage, including corrosion in steel, stress in aluminum, impact and delamination in carbon fiber reinforced polymer (CFRP) laminates, and RCF cracks in rail tracks Book jacket.
