This study analyzed the static compression performance of honeycomb paper-core. Based on the finite element analysis software, the static compression process of honeycomb core layer was simulated. The deformation, stress distribution and other processing pictures in different displacements were obtained. The simulation results were consistent with the experiment results. Crush started at the top of the core layer. There were yield waves in the elastic-plastic stage and the number of yield waves increased in stair-step shape along with the increase of side length. Stress distribution showed that load bearing transferred from the honeycomb panel to the cellular edge along with the increase of displacement, which can explain the tackless at adhesion due to stress concentration in experiment.
