title = "Characteristics of acoustic emission signals in integrally stiffened aluminium plates",
abstract = "Two dimensional numerical models were established with the SPH (smoothed particle hydrodynamics) technique of AUTODYN hydro-codes in this paper. The acoustic emission (AE) signals produced by hypervelocity-projectile impact in integrally stiffened aluminium plates at normal were obtained under the condition of different stiffener widths. The influences of integrally stiffeners on AE signals and on impact localization were investigated. The analytical results show that the stiffener width has more effect on the first amplitude of acoustic emission signals from the stiffeners than that from the other parts. Therefore, the acoustic emission sensors should be attached away from the stiffeners in order to reduce the effect on the precision of impact localization.",
