Finite Element Analysis of Composite Circular Honeycomb Structure.

Panels made using honeycomb sandwich technique can help aerospace manufacturers maintain weight and fulfill certain strength requirements. Rigidity, stress absorption, fatigue resistance, and resistance to weather, chemicals, fire and isolation are some of the key benefits of honeycomb panels. Due to mechanical and acoustical requirements for high strength and weight target, it is common to select a sandwich design with a cheap and recyclable core material. Among other things, honeycomb sandwich structures are used in ship hulls, automobiles and civil constructions. Usage of these designs is the best way to obtain high strength and title material utilization. In this paper, the designs of hexagonal and square honeycomb constructions are evaluated for the most favorable structural outcomes. A honeycomb panel was produced using SolidWorks software. The proposed model was subjected to structural analysis using LS-DYNA software for four distinct kinds of materials: copper, steel, titanium and aluminum. Finally, the simulation results are presented and discussed. [ABSTRACT FROM AUTHOR]
