This study attempts to study the effect of geometric and mechanical properties on the bending behaviour of simply reinforced sandwich beams. According to the theory of simple beams. We used ABAQUS 2016 and the C3D8R element type with a consistent mesh size of 2 mm to simulate a three-point bending configuration with displacements of 0.1 mm to 0.6 mm. Tangential behaviour was used to simulate contact interactions. Numerical results for stresses and displacements were calculated. We modelled the bending behaviours of two models of aluminium alloy EN AW-1050A beams loaded with imposed displacements by bending. The comparison was made using a honeycomb sandwich beam as a reference model that we developed from simulations. X core had the most displacement (up to 2.812 µm), which meant it was very flexible but not very strong; O core had the least displacement (up to 3.672 µm), which meant it was very stiff; and NIDA B core had behaviour in between (maximum displacement around 4.472 µm). The presented models are suitable for studying bending on a simple, supported sandwich beam subjected to intense mechanical loads used in special technical applications in the aerospace, automotive, and civil engineering industries.
