Abstract

Fatigue damage in laminated composite plates has been detected using ultrasonic guided waves. The quasi-isotropic plates were subjected to constant amplitude cyclic bending to induce fatigue damage. Cycling was automatically interrupted periodically for ultrasonic monitoring via an array of six piezoelectric sensors. Nine different pitch-catch paths and a frequency range of 100-600 kHz were used to study the effect of damage on guided wave propagation. The signal difference coefficient was consistently able to provide an early indication of damage.
