The main goal of the paper is a comparison of three non‐linear hypotheses of deformation of flat cross sections of an elastic sandwich beam. Three‐layered simply supported beam is under uniformly distributed load (pressure). Studied beam has two faces and a metal foam core. Mechanical properties of the isotropic metal foam core of the beam vary across the thickness of the beam. Fields of displacements (geometric models of non‐linear hypotheses) are described. The results of solution of the deflection problem are presented at Figures. (© 2009 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
