Design Parameter Optimization Of Thin-walled Structural By Implementing Beetle Forewing Sandwich Structure Model Using The Multi-factor Experimental Design

Abstract

Abstract The adaptability of the beetles lets this ancient genus avoid extinction. The robust body construction of the beetles is the physical result of the creation process which enhances the performance potential of this insect. Human beetles are unique and comprise of forewings and hind wings. Forewings are layers of light and solid wings that cover underneath the hind legs. The framework for the forewings promotes a lightweight system known as the Beetle Forewing Sandwich Structure (BFS). The structure of the BFS is related to the existing honeycomb sandwich structure at different hexagonal wall sites with additional trabeculae. Previous studies showed remarkable mechanical performance of this structure over conventional lightweight structure (e.g., hexagonal plate) in BFS. In the present review, an enhancement analysis will be carried out to optimize the role of the BFS design through multi-factor experimental design method, with material used is Aluminum 6061 Alloy (UNS A96061) proposing a BFS structure with greater intensity but less weight. Eventually, the findings of this study that contribute to the alternative lightweight framework for many engineering applications, especially the load-bearing goods.
