dc.description.abstractThis study represents the interaction of A0-mode Lamb wave at a cylindrical hole in composite laminates focusing on its
dc.description.abstractscattering characteristics. A 3-dimensional Finite Element Modeling (FEM) is used to discuss the effect of the stacking
dc.description.abstractsequence in the wave propagation. An excitation signal of 30 kHz, modulated by Hanning window is allowed to propagate
dc.description.abstractwith plane strain condition in a defected squared shape laminate. Propagations of Lamb wave in 8-layered composite
dc.description.abstractlaminates with an identical defect are considered. It is found that the reflecting and transmitting characteristics of the
dc.description.abstractincident wave dominated by the outermost layer and the pattern varied with different stacking sequences. The outcomes of
dc.description.abstractthis computational study help to the use of the A0-mode Lamb wave for damage characterization and detection in composite
dc.description.abstractlaminates.
