Abstract

This study presents a comprehensive investigation into the static structural analysis of honeycomb structures utilizing the finite element method (FEM). Honeycomb structures are renowned for their lightweight yet robust characteristics, making them pivotal in various engineering applications. However, challenges persist in optimizing these structures to achieve desired strength, minimize weight, and reduce costs. The research focuses on three key parameters: dimension, materials, and shape, with the overarching objective of evaluating the structural performance of honeycomb configurations under diverse conditions. The preprocessing stage involves CAD modelling, followed by the transfer of models to ANSYS for discretization (meshing). Subsequently, ANSYS's automated capabilities are leveraged to generate simulations, and post-processing techniques are employed to analyse critical metrics such as stress, strain, and deformation. The dimensions parameter explores variations in wall thickness (1.1mm, 1.2mm, 1.3mm) to assess their impact on structural integrity. Material selection encompasses titanium alloy, aluminium alloy, and magnesium alloy, reflecting commonly employed materials in aerospace and automotive industries. Furthermore, the study investigates the influence of different shapes (Shape 1, Shape 2, Shape 3) on structural performance. The outcomes of the analysis facilitate the identification of optimal honeycomb structures for each parameter combination. By systematically evaluating these configurations, this research aims to provide insights that can inform the design and manufacturing processes, ultimately leading to the development of honeycomb structures that are simultaneously strong, lightweight, and cost-effective.
