Numerička analiza dinamičkog ponašanja kompozitnog saćastog panela ispunjenog cevčicama pod dejstvom udarnog opterećenja male brzine u ravni panela

Honeycomb sandwich structures, composed of many regularly arranged hexagonal cores and two skins, show excellent impact performance due to strong energy absorption capability under impact loads. In this paper, a numerical study of low velocity impact on honeycomb sandwich panels filled with circular...
