In the present study, analytical expressions for critical loads are derived and eigenvalue and post buckling analysis are performed on the panels, using the finite element method, using the commercial software ABAQUS. Genetic algorithm is used to optimization of sandwich panels with periodic, open-cell cores, observing yielding and buckling in components as optimization constraint and then minimum weights for some load capacities are determined. Design variables and cost function are defined as non-dimensional and optimal results are shown by diagrams.
