Fatigue Crack Detection Using Nonlinear Acoustic-Analysis Of Vibro-Acoustic Modulation

Nonlinear vibro-acoustic is a highly reliable and sensitive method for damage detection. It is a method based on propagation of high frequency acoustic waves in solid structures with low-frequency excitation. Interaction of the acoustic wave with material or geometry properties changes caused wave d...
