Abstract

Impact behavior of sandwich panels with auxetic and hexagonal honeycomb cores are investigated experimentally and numerically. Re-entrant and anti-tetrachiral geometries are considered for auxetic cores. In the experimental side of the study, auxetic and honeycomb cores are produced using a 3D printer. The sandwich panels are then produced by attaching aluminium face sheets and cores. The impact tests are performed using a particle impact test system. The numerical analyses are achieved by using LS-DYNA finite element software. The deformation results are compared and the effect of having different type of core is evaluated.
