Aluminum honeycomb sandwich structures are crucial for enhancing the efficiency of aircraft, trains, and ships due to their lightweight characteristics. This study aims to analyze the homogenization and bending strength properties of a lightweight honeycomb sandwich structure made of aluminum. A numerical three-point bending test was conducted on the sandwich structure using the Digimat-HC module. The study revealed a non-linear increase in von Mises stress, energy absorbed, and vertical displacement of the mid-section with respect to indenter load. The failure load for the sandwich structure was determined to be approximately 7.6 kN. Stress analysis showed that the layers (skins) absorbed the maximum stress, with minimal stress transferred to the core. The investigated sandwich structure exhibits promising characteristics for impact applications, as indicated by the stress distribution favoring the layers over the core. This study contributes valuable insights into the design and performance of aluminum honeycomb sandwich structures, which may have potential patent implications in the field of lightweight structural materials.
