The compression behavior of a sandwich panel based on a millimeter honeycomb structure was modeled using the Finite Element Method (FEM). For the modeling process, AA7075-T6 aluminum was selected due to the wide applications that this material has in the addictive manufacturing of different types of parts with diverse applications. Different pressure values were applied to evaluate the influence that this variable has on the deformation, displacements and stresses acting on the honeycomb structure. The design of the parts was carried out using the professional software SolidWorks version 2020 PREMIUM, which contains a modeling package that uses the FEM for the modeling of parts subjected to different loading conditions. The results allowed us to determine that the millimeter honeycomb structure, modeled in this work, is capable of absorbing loads of up to 30 MPa without suffering appreciable deformations, even when the yield limit of the material and the safety factor of the structure reach are exceeded values less than one. The simulation carried out allowed us to determine the zones of linear-elastic regime and post-yield stress and densification of the panel based on a honeycomb structure.Downloads
