Journal ArticleDOI
Surface Crack Detection for Carbon Fiber Reinforced Plastic (CFRP) Materials Using Pulsed Eddy Current Thermography
Liang Cheng,Gui Yun Tian +1 more
TL;DR: In this article, a PEC thermography inspection system for carbon fiber reinforced plastic (CFRP) materials is studied and optimized, and the authors show that PEC can be used for defect detection and characterization through analysis of the surface heating pattern and the transient temperature change.
Journal ArticleDOI
State Detection of Bond Wires in IGBT Modules Using Eddy Current Pulsed Thermography
TL;DR: In this paper, the eddy current pulsed thermography (ECPT) was used for the state detection and characterization of bond wire lift-off in IGBT modules, which is the most common failure mechanism in bipolar transistor (IGBT) modules.
Journal ArticleDOI
Comparison of Nondestructive Testing Methods on Detection of Delaminations in Composites
Liang Cheng,Gui Yun Tian +1 more
TL;DR: Comparison and evaluation of the new developed PEC thermography system at Nanjing University of Aeronautics and Astronautics (NUAA), China are conducted, and it is shown that PEC-stimulated thermography has unique advantage for fibre orientation evaluation.
Journal ArticleDOI
Impact Damage Detection and Identification Using Eddy Current Pulsed Thermography Through Integration of PCA and ICA
TL;DR: An integration of principal components analysis (PCA) and independent component analysis (ICA) on transient thermal videos has been proposed, which enables spatial and temporal patterns to be extracted according to the transient response behavior without any training knowledge.
Journal ArticleDOI
