TL;DR: In this paper, a review of modeling approaches used for nonlinear crack-wave interactions is presented, including models of crack-induced elastic, thermo-elastic and dissipative nonlinearities.

TL;DR: In this article, the authors focus on localisation of damage-related nonlinearities based on higher harmonic generation and show that cracks are particularly strong in the vicinity of damage, allowing not only for damage localisation but also for separation of crack induced nonlinearity from other sources of non linearities.

TL;DR: In this article, a low-degree-of-freedom model of an epicyclic gearbox which incorporates the possibility of simulating tooth faults, as well as any subsequent tooth contact loss due to these faults, is introduced.

TL;DR: A growing interest in non-destructive testing methods based on nonlinear acoustics have been observed for the last ten fifteen years The majority of methods in this area take their origin from the observation that fatigue damaged materials often behave like mesoscopic nonlinear materials (eg rocks) in which nonlinear phenomena such as higher harmonics generation, vibro-acoustic wave modulations, amplitude dependent resonance frequency shift and slow dynamic effects are observed for years as discussed by the authors.

TL;DR: In this paper, the authors investigated the effect of crack-induced nonlinearity on the dynamics of a beam with a breathing crack excited longitudinally, and found that the crack induced non-linearity had a localized effect on dynamics of the beam.
