“…The analysis of the wave propagation near the holes is complicated because of the reflections from the boundaries [9,10]. However, there are methods for monitoring the state of the hole edge during the fatigue tests [11][12][13][14]. The prognosis of the fatigue life with the use of wave propagation method is also possible and verified in experimental testes [15,16].…”

Abstract. In this paper the elastic wave propagation method was used to observe the evolution of the failure form in composite multilayered plates with a circular hole. The measuring system based on two, surface-mounted piezoelectric (PZT) elements was applied. The sequential measurements of the elastic wave propagation during the fatigue test have been carried out. The Time of Flight (ToF) parameter defined as a time between guided wave excited by an actuator and the first wave captured by a sensor was introduced to observe the behavior of the defected structure. Monitoring of the (ToF) parameter during the fatigue test has been applied to estimate the state of the structure.

“…The modulating stress may be produced by different means, such as external cyclic loading in a typical fatigue test [5,6] or exploiting the inherent vibration of the structure itself during operation [7]. The main disadvantage of using external mechanical loading is that usually the whole structure must be loaded, which requires very substantial forces and might cause additional damage in certain parts of the structure.…”
