title = "A study of the effects of structural delamination location on delamination detection using a non-linear chaotic oscillator method",
abstract = "This work aims to investigate the effects of structural delamination location on the effectiveness of delamination assessment using a vibration-based non-linear chaotic oscillator method. The effects of vibration measurement locations on the sensitivity in detecting the location of delamination were investigated. In this work, a chaotic oscillator method was used due to its sensitivity to relatively small changes in measured vibration signal and robustness to measurement noise. The Lyapunov Exponent was used in conjunction with the chaotic oscillator as a damage index, for the purpose of defining an effective measure to locate the delamination damage in a laminated structure. The relationship between the damage index and vibration measurement location for different delamination locations was investigated for a delaminated beam structure. It was found that the vibration measurement location can highly influence the sensitivity of the vibration-based chaotic oscillator method for delamination assessment.",
