WebThe objective of this study was to predict the buckling of an elliptic delamination embedded near the surface of a thick quasi-isotropic laminate. The thickness of the delaminated ply group (the sublaminate) was assumed to be small compared to the total laminate thickness. Finite- element and Rayleigh-Ritz methods were used for the analyses. Webcommonly termed as Bleustein-Gulyaev (BG) wave. BG wave is a non-dispersive surface wave which exists only in piezoelectric materials. Like the Love wave its particle motion is entirely transverse and parallel to the surface, but it is confined to the surface by the piezoelectric effect rather than by a layer of a different material.
WebThe propagation of Rayleigh and Stoneley waves on boundaries with topography has been treated using an approximate method. Where subsurface layering is not important, the properties of boundary waves are controlled by the shape of the boundary. Arbitrary linear topographic features have been approximated by a series or cylindrical surface … WebIt not only determines the incentive efficiency of SAWs (assuming that interdigital transducers (IDT) [11], [12] are used to generate these waves), but also influences the sensitivity of some sensors [13], [14], [15] used for detecting electrical properties of …
