The objective of this work is the numerical analysis of the stability of three-layered beams with a metal foam core. The beams were subjected to three-point bending. The analysis of the local buckling and the influence of material properties of the faces and the core on critical loads and buckling shape was performed. The calculations were made in elastic range on a family of beams with different mechanical properties of the faces and the core. Calculations of critical loads and buckling shape were performed. The analysis of the finite element model (FEM) of three-layered beam has been performed with the use of ANSYS software. The upper and the lower face have been retreated from the core by half of the thickness. Tie constrains have been applied between the core and the faces. Due to symmetry of the model only a quarter of the beam has been modelled with proper boundary conditions on the symmetry planes.
