For mechanical system structural health monitoring, a new residual generation method is proposed in this paper, inspired by recent result on subspace identification. It improves statistical properties of the existing residual, which has been naturally derived from standard identification method. Replacing monitored state-space model Kalman filter one-step ahead predictor key element improvement...

The influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. The incorporation of nanoclay into epoxy enhances the impact resistance of the composites. The impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...
