The structure is generated by Voronoi tessellation, and it is considered as composed by rod-beam members with six degrees of freedom. A combination of continuum mechanics equations and finite element analysis is applied to evaluate the model response when undergoing dynamic external input. Specifically, the significance of wave propagation modes is studied with main interest in twisting waves. 000014095 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000014095 653__ $$a 000014095 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000014095 720__ $$aMartinez Pavetti, Belen 000014095 8560_ $$ffischerc@itam.cas.cz 000014095 8564_ $$s215865$$uhttps://invenio.itam.cas.cz/record/14095/files/PO.FS09-2.01.278.pdf$$yOriginal version of the author's contribution as presented on CD, page 3460, code PO.FS09-2.01.278 . 000014095 962__ $$r13812 000014095 980__ $$aPAPER
