Abstract :

 Sandwich panels with high modulus/high strength skin material and low density/low modulus core material have higher stiffness–to–weight ratio than monolithic panels. In this paper, sandwich panels with corrugated core are explored as a light weighting concept for improved stiffness. The skin and the core materials are a high strength stainless steel, aluminum alloy or carbon fiber–epoxy composite. Corrugated open metallic sandwich structures are novel type of structures. Flexural modulus is a basic property of the material in such faicated open core structures welding by spot welding. In the present work spot welded metallic panels are used to optimize the geometry. Based on the analysis, panel structure parameters considered are Thickness of the sheet, Core height, Core shape, Panel size and Material constituents of panel face sheet, bottom sheet and core. The parameters are analyzed by Taguchi design of experiments by considering orthogonal array of L9. The main aim is to optimize the panel dimensions of a faicated metallic panel, using Finite Element Analysis. The results show that the proposed approach can find optimal dimensions considering both better and more robust design.
