Such a distribution of property shows a localization of the vibration in the low stiffness and low density part of the structure. A finite element model is compared to analytical approach based on WKB method for inhomogeneous wave guide for a better understanding of the parameters governing energy localisation in these structures. 000014370 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000014370 653__ $$a 000014370 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000014370 720__ $$aBen Lassoued, Mohamed, Amin 000014370 8560_ $$ffischerc@itam.cas.cz 000014370 8564_ $$s175924$$uhttps://invenio.itam.cas.cz/record/14370/files/PO.SM16-1.02.212.pdf$$yOriginal version of the author's contribution as presented on CD, page 3007, code PO.SM16-1.02.212 . 000014370 962__ $$r13812 000014370 980__ $$aPAPER
