dc.description.abstractApkrautos daugiasluoksnės polimerinės plėvelės virpesiai tirti skaitmeniškai, priimant, kad plėvelė sudaryta iš trijų sluoksnių. Viršutinis ir apatinis sluoksniai yra stan-dūs ir nesideformuoja skersine kryptimi, o vidinis sluoks-nis gali deformuotis šia kryptimi. Analizuojamos pirmos savosios formos ir pateikti grafiniai jų tyrimo rezultatai. Apkrautos daugiasluoksnės polimerinės medžiagos PET+POP+ŽTPE (PET+POP+ŽTPE žymi trisluoksnę me-džiagą, sudarytą iš PET – PoliEtileno Tereftalato, POP – POPieriaus ir ŽTPE – Žemo Tankio PoliEtileno) eksperi-mentai buvo atlikti žadinant šią medžiagą priverstiniais virpesiais. Pirmos savosios formos buvo gautos naudojant skaitmeninės raibumų fotografijos metodą ir buvo nustaty-ta, kad savosios formos kinta keičiant sužadinimo dažnį. Gauti skaitmeninių tyrimų rezultatai palyginti su eksperi-mentiniais. Gauti tyrimų rezultatai taikomi nustatant pakavi-mo medžiagų charakteristikas ir savybeslt
dc.description.abstractVibrations of a loaded multilayered polymeric film have been investigated numerically by assuming that the film consists of three layers. The upper and lower lay-ers are stiff and do not deform in the transverse direction, while the internal layer can get deformed in that direction. The first eigenmodes are analysed and graphical findings of their investigation are presented. Experimental tests on the loaded multilayered polymeric material PET+PAP+LDPE (PET+PAP+LDPE denotes three-layered material made from PET – Poly-Ethylene Tereph-thalate, PAP – PAPer and LDPE – Low Density Poly-Ethylene) have been performed by exciting this material by forced vibrations. The first eigenmodes have been obtained by using the method of digital speckle photography, and it has been determined that eigenmodes change with the change of the excitation frequency. The obtained results of numerical investigations are compared with the experi-mental ones. The obtained study results are applied in deter-mining the characteristics and qualities of packaging mate-rialsen
