Active infrared thermography is a fast and accurate non-destructive evaluation technique
that is of particular relevance to the aerospace industry for the inspection of aircraft and …

Barely visible impact damage (BVID) is inevitable during either fabrication or lifetime of a
carbon fiber reinforced plastic (CFRP) component. These flaws are usually difficult to be …

Hybrid smart actuators fabricated using composites of carbon fibers and shape memory
polymers have been extensively studied in recent years. However, relatively slow shape …

Coating debond, caused by thermal stress, is inevitable during the service of thermal barrier
coatings (TBCs) in gas turbine engines. This study investigated detection of coating …

Vibro-thermography is a promising nondestructive testing technique owning to its full-field
and defect-selective imaging which excites ultrasonic waves to locally stimulate defects in …

Composite sucker rods are becoming increasingly popular in oil fields owing to their light
weight and corrosion resistance. However, various defects may appear in the manufacturing …

Due to its induction heating mechanisms, eddy current pulsed thermography (ECPT) is
always used as Non-destructive testing (NDT) technique only for conductive materials. This …

The hot gas components in a gas turbine have to withstand extreme loads. As failure of
turbine blades could have catastrophic consequences, the integrity of the entire engine must …

In this paper, terahertz (THz) imaging and vibro-thermography (VT) are implemented for non-
destructive evaluation (NDE) of CFRP subjected to impact damage. THz inspection is well …

Debonding defects are common and they are the main reason for the failure of hidden frame
supported glass curtain walls, which are widely used as an external enclosure and …
