Open core metallic sandwich panels are novel type of structures, enabled by innovative fabrication and topology design tools. Flexural modulus is a basic property of the material in such fabricated 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 L36.The main aim is to optimize the panel dimensions on flexural modulus of a fabricated metallic panel, using Finite Element Analysis. The problem is modeled in ANSYS and the flexural modulus is evaluated in the transverse direction by three point bending test (ASTM D790). The optimum dimensions are evaluated by Taguchi Analysis. The results show that the proposed approach can find optimal dimensions considering both better and more robust design.
