Resonance testing
Posted by: S S Ananthan (PID_644), E-mail: ananreva@yahoo.com, on December 27, 2003 at 18:02 :
HEllo,
I understand that there is a method called resonance testing which uses the natural frequency of a job to identfy whether it has any defect by comapring the natural frfequency of a defect free job.
Is it used in detecting defects in welding ? Any specific experience ? Can the method be used for detecting stiffness of structures ?
