Received: 9 May 2020 Accepted: 3 June 2020 Sandwich structures are low-weight and have the best stiffness and a relatively high flexural strength, what makes using them continues to increase rapidly for industrial applications ranging from aeronautics, road vehicles, satellites, ships and civil engineering to mention only a few. The paper presents investigation and analysis of the behavior of composite sandwich beams with polyester resin/glass fibers skins (T800/M300) and aluminum honeycomb core under unsymmetrical bending impact. In this work we propose a numerical study using a calculation software, structural analysis by finite element method (CAST3M), for determining the stresses and displacements. The results which have been obtained after numerical modeling showed that unsymmetrical bending resistance of the sandwich beam is dependent largely on the skins.
