'''Keywords:''' DOE ; Metamodeling; Pareto optimality; Virtual prototyping; Response surface;

'''Purpose:''' The aim is to investigate an innovative solution for a multifunctional sandwich panel. Moreover ,a specific objective of this paper is to test different models of cells type and different skin thicknesses to understand which design variable affect mainly the mechanical behavior .

'''Methodology:''' To establish whether of the design variable affects majorly the mechanical resistance of the sandwich panel, a Design of Experiment (DOE) has been designed. DOE method has been applied through FEM simulations on a NACA profile, using real loads from aerodynamic simulations. FEM model considers the outer skins modelled as shells and the lattice core made by beams. So that, DOE design variables considered in the present work are: cell type, cell length, beam section radius, shell thickness. FEM geometry (cell type and length) was set-up through a MATLAB code designed for automatize the FEM pre-processing.

'''Findings:''' From the Pareto frontier of the problem, optimal solutions were evaluated. To optimize mass and 1st frequency beam radius can be set between 0.35 and 0.40 passing from cell_1 to cell_2_ in case of length_5, from 0.47 to 0.50 in case of length_7. Shell thickness, with the same type of progression, changed from 0.52 to 0.40.

'''Benefits:''' The adopted DOE allowed to build a full quadratic response surface that was used to optimize mass and frequency, leaving the maximum stresses under a threshold safe for yielding.
