Damage Detection, Localization and Assessment in Multilayered Composite Structure with Delaminations

In this paper the dynamic behavior of composite multilayered cylindrical panel with a single, square, interlaminar delamination is considered with using finite element method. Based on numerical results it is possible to determine the effect of the delamination on the guided wave propagation in curved structures. The results are used to quantify the difference of response signal in the case of perfect and defected structures. The results indicates that the size and orientations of the defect have a significant influence on overall dynamic behavior and they should be taken into account to design appropriate and effective non-destructive damage test methods and algorithms.
