Analysis of acoustic emission signal generated by timber under load

Acoustic emission monitoring of wood materials and timber structures: A critical review

“…AE has become one of the standard NDE tools used in monitoring the failure processes in wood, wood-based products, and other composite materials [97,98]. Some AE parameters used in understanding the material's failure, including the AE amplitude, AE count, and AE hits, have been reported in the literature [99]. Several approaches have been implemented in investigating the likelihood of failure monitoring using AE.…”

“…For instance, several studies found a direct correlation between AE signals and cracking (initiation and propagation) in timber structures [98,122,124]. Similarly, timber's properties, such as bending stress, deformation, and material cracking which are pointers of fiber damage, were successfully monitored using the AE technique [99,122,125]. Some authors also revealed the likelihood of detecting the location of damage in wooden boards by AE monitoring [126].…”
