Non Destructive Evaluation (NDE) of Aircraft Structures.

Elliott Cramer of NASA Langley Research Center's Nondestructive Evaluation Science Branch (NESB) has been using DeltaTherm for Non Destructive Evaluation (NDE) of aircraft structures. He reports being very pleased with the results, and talks briefly about the inspection of a particular part. "[We] used the DeltaTherm to successfully image the stresses in a door latch assembly experiencing dynamic loading" (shown below) "This work was done to confirm finite element modeling of the stress distribution in that part. A series of additional tests and demonstrations of the capabilities of the DeltaTherm are being planned for the near future."
