The sandwich structure is of great interest because of its advantage of combining\nlight weight and high flexural stiffness. Many previous researchers have\nstudied the failure modes in sandwich structures and the effects on the load\ncapacity caused by the change of the constituent materials� properties. In this\nresearch, by applying Finite Element Analysis (FEA) method, we simulated a\ncantilever beam composed of a sandwich structure in Abaqus, to find out the\npreferred design principles that help decrease the stress and displacement in\nthe beam when applied a uniform load. We also determined the effect of the\ncore geometry on decreasing the displacement and the stress in the beam.
