The phenomenon of the Lamb wave interaction with fatigue crack in Al2024-T3 sheet
was investigated at cyclic loading. Mentioned effect is associated with the crack open/close that
change acoustic impedance of a crack. Analytical simulation of fatigue crack opening using the
generalized Dugdale’s model of a crack in thin plate shows good accordance between the intensity
of ultrasonic signal and a crack opening.
