The thin-walled plate and foam of low material is components of sandwich panels, one of the attractive engineering
structures mixed between different two materials to accomplish high ultimate strength integrated with light weight
structures. Usually, the sandwich panels composed of two thin steel faces with ultra-strength are supported and
separated between them by foam core. This paper deals with presently design expression of thin-walled steel faces
supported by foam simulated using finite element analysis (FEA). Numerous waves of FE models introduced to explore
and analyze the adequacy of present approach for thin-walled design. Also, investigation of FE simulation model
containing geometry, dimensions, loading system and supporting pattern are presented. The FEA model provides a good
acceptance with experimental results. However, for sandwich plate element with low (b/t) ratios, the formulae of design
appeared safety solution, while for high (b/t) ratios (slenderness plate) becomes over estimated. Finally, formula of
designing sandwich plate with local buckling is proposed in unification form.
