The subject of the paper is a symmetrical seven layer beam with foam cores. The beam consists of the main core, two inner sheets, two outer cores and two external sheets. The cores are metal foams, while the sheets are metal. The analytical model of the beam is developed. The displacement is formulated with consideration of the zig-zag hypothesis of deformation of a flat cross-section of the beam and the governing differential equations for the considered beam are derived based on the stationary total potential energy. The studies are devoted to deflections of the beams under a three point bending. The influence of the different types of cores and faces on the deflections of the beam is analyzed. Moreover, the numerical FEM-model of the beam is presented in two different FEM programs: ABAQUS System and SolidWorks Simulation. The results of the analysis are presented in Tables and Figures.
