Sandwich constructions with honeycomb design offer a viable route toward high-strength, lightweight technical uses. This work uses finite element analysis (FEA) software to do a mechanical analysis of such sandwich structures under axial compression. The goal of the study is to comprehend how these sandwich constructions with honeycomb designs behave structurally and function under compressive loads. Various characteristics, such as stress and deformation, are investigated by FEA simulations to assess the sandwich panels’ structural integrity and load-carrying capacity. The obtained results aid in the optimization of the design of the honeycomb sandwich structures for improved strength-to-weight ratio and structural efficiency by shedding light on their mechanical response. In the automotive, aerospace, and numerous other fields where reducing weight and structural strength are crucial, the current study advances engineering approaches for the design as well as evaluation of structures that are lightweight.
