摘要

Honeycomb structures, known for their lightness and strength, find applications in various sectors such as aeronautics, automotive, civil engineering and defense. These structures are particularly effective in reinforcing areas subject to specific constraints, thus providing optimal mechanical performance. This study aims to analyze the mechanical behavior of aluminium honeycomb structures, particularly hexagonal and star-shaped, under compression, and to optimize their resistance by combining their geometric advantages with the integration of hybrid reinforcements. To achieve this objective, a numerical model was developed using the finite element method and implemented via the Abaqus/Explicit solver (version 6.17). Validation of this model was carried out through experimental tests to ensure the accuracy of the results and the reliability of the model. The obtained results show an excellent correlation with experimental data for the hexagonal structure, with a deviation of 8.25% for the maximum load and 4.89%. The SHS structure has a second plateau representing approximately 26.95% of the maximum load, while the advanced hybrid structure, which combines internal reinforcements and double walls to optimize rigidity and stability under axial load, has a second plateau of 86.32%. This difference clearly illustrates the enhanced potential of the hybrid configuration for demanding industrial applications, particularly in aerospace.
