Abstract
Honeycombs are essential elements in mechanical systems where low weight and high
strength are required. Aluminum and Nomex® are the most commonly used honeycomb
materials in structures exposed to compression stress. The primary purpose of this study is
to verify the compression behavior of honeycombs in Ls-Dyna using experimental values and
theoretical equations. Additionally, it is aimed to evaluate the honeycombs parameters such
as cell diameter, cell wall thickness, and material. A correlation matrix was created using the
Python/Seaborn program to examine the impact coefficients of the parameters. In this way,
the effect of design parameters on compression strength and internal energy was investigated.
