This study conducts a numerical investigation into the response of a honeycomb sandwich structure cube under internal blast. Three different types of honeycomb core structures with varying numbers of sides were designed to withstand internal blast loads. Numerical simulations were performed using LS-DYNA, applying the same material and volume for the honeycomb core to evaluate the effect of core geometry. Both the honeycomb and steel cube were meshed with shell elements using a default element formulation, with the back plate defined as a fixed support to induce uniform deformation. The Johnson--Cook Material Model was applied for material behavior. Results indicated that as the number of sides of the honeycomb core increased, the front plate experienced less damage, demonstrating improved blast resistance. These findings suggest that optimizing the geometry of honeycomb cores can enhance the energy absorption capacity of structures, making them suitable for protective applications in blast-resistant designs.
