dc.description.abstractThe present study proposes a detection technique for delaminations in a laminated composite structure. The proposed technique optimizes the spatial distribution of harmonic excitation so as to magnify the difference between the delaminated and intact structure. The technique is evaluated by numerical simulation of two-layered aluminum beams. Effects of measurement and geometric noises are included in the analysis. A finite element model for a delaminated composite, based on the layer-wise laminated plate theory in conjunction with a step function to simulate delaminations, is used.en
