In situ measurement of fatigue crack opening stresses by nonlinear vibro-acoustic modulation testing
The difficulty of accurately measuring crack closure regions has hindered measurements of opening or closure stresses, and ultrasonic methods have shown great potentialities in evaluating closure area. Many recent researches have confirmed the advantages of nonclassical nonlinear acoustic approaches...
