Boeing Defense and Space Group in Kent, WA is investigating forced harmonic shearography nondestructive testing technique for detection of disbonds in bonded structures of both existing nd future generation aircraft. This paper describes the forced harmonic shearography inspection technique by using real time electronic shearography and sine swep vibration system. Results from NDI of aluminum bonded and composite bonded structures will be shown.
