Brief abstract:

This projects aims at investigating the different modalities of thermographic inspection methods (passive, active, selective, global) for the non-contact, real-time testing of adhesive bonded structures. New stimulation methods are developed and used in addition to new optical systems. 


Impact:

100% inspection of adhesively bonded vehicular structures.

Project schedule:

Initiated in 2008 and completed in 2009
