Abstract:V magistrskem delu so predstavljene mehanske in frekvenčne analize kiralnih avksetičnih struktur. V odvisnosti od geometrijskih parametrov strukture je bilo z eksplicitnimi dinamičnimi analizami izračunano Poissonovo razmerje s programom LS-DYNA. Predstavljeni rezultati prikazujejo vpil geometrijskih parametrov na velikost Poissonovega razmerja. Prav tako so bile izvedene frekvenčne analize z željo ugotoviti območja prepovedanih frekvenc v odvisnosti od stopnje avksetičnosti. Območja prepovedanih frekvenc so bila izračunana z Blochovo valovno analizo v programu ABAQUS. Glede na izračune se vidi vpliv stopnje avksetičnosti velikosti območij prepovedanih frekvenc. Ugotovljeno je bilo, da se pri večanju stopnje avksetičnosti pojavijo dodatna območja prepovedanih frekvenc.

Title:Influence of auxetic level on the forbidden frequency gaps of chiral structures
Abstract:This master thesis presents the mechanical and frequency analyses of auxetic chiral structures. In dependence of geometrical parameters, a Poisson’s ratio study was done with explicit dynamic analyses in the program LS-DYNA. The presented results shows the influence of geometrical parameters on the Poisson’s ratio. In addition, a frequency study is presented with the goal to determinate the influence of auxetic level on forbidden frequency gaps. Bloch wave analysis was used to calculate forbidden frequency gaps in the program ABAQUS. From these results, the influence of auxetic level on the size of forbidden frequency gaps is shown. It was found out, that with increasing the auxetic level new forbidden frequency gaps appear.
Keywords:Auxetic structures, Poisson's ratio, LS-DYNA, Bloch wave analyses, Bloch's theorem, forbidden frequency gaps, ABAQUS
