On the interaction of ultrasound with cracks: Applications to fatigue crack growth [PDF]
Partial contact of two rough fatigue crack surfaces leads to transmission and diffraction of an acoustic signal at those contacts. Recent experimental and theoretical efforts to understand and quantify such contact in greater detail are discussed.
