Surface Crack Detection for Carbon Fiber Reinforced Plastic (CFRP) Materials Using Pulsed Eddy Current Thermography

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

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

Inspection and Structural Health Monitoring techniques for Concentrated Solar Power plants

TL;DR: In this article, non-destructive evaluation techniques that can be employed to inspect solar receivers and insulated pipes as well as relevant research and development work in this field are discussed, and a discussion of the nondestructive inspection of solar receivers can be found.
