A Comparative Study on the Finite Element Analysis of Multilayered Honeycomb Composite Materials for Aerospace Structures.

Honeycomb composite materials are widely used in many areas of mechanical engineering where weight saving is a crucial factor. One of the main loads that such material configurations are designed to withstand is compressive load. The most important industrial sector where honeycomb composite materials have found their application is in the aerospace industry, due to their advantages of high strength and lightness. In this article, two forms of finite element model analyses are presented for a novel multilayered honeycomb composite material with impregnated paper cores. The first represents a detailed approach tailored for local analysis, while the second is useful for a global analysis of the honeycomb composite material. Both types of modeling techniques are presented with a description of their advantages and drawbacks, highlighting the increased precision of the complex model-closest deformation estimations-and the agility of the equivalent one-an 80% reduction in complexity, providing acceptable results. An initial comparative analysis is performed, and the obtained results are discussed. An experimental validation is also carried out, followed by the presentation of a suggested practical application, displaying good accordance.
