Early detection and characterization of damages in materials are important to control the durability and reliability of parts and materials in service. In this study we considered the harmonic generation method for the detection of closed crack. Measurements were carried out on a real fatigue crack using harmonic generation method. Numerical analysis was performed using a 2D FE model describing the interaction between plane longitudinal acoustic wave and its interaction with a contact interface. Different contact interface profile had been studied, showing specific evolution of the amplitude of the second harmonic as function of applied force. [ABSTRACT FROM AUTHOR] |
