Abstract
This paper aims to construct a lightweight and durable structure with different designs and construction methods using materials with low-weight characteristics and appropriate strength. In this regard, sandwich panels were made in filled and unfilled sine and square corrugated core, and for comparison of some mechanical behaviors of made specimens with each other, three-point bending tests were performed. Obtained results indicated that the use of polyurethane foam will significantly increase the energy absorption of the structure and extend the life of the structure. The amounts of absorbed energy of the foam-filled samples are 2 and 2.5 times of the foam-free ones for sine and square corrugated cores, respectively. Finally, a numerical analysis based on finite element solution using ABAQUS software by applying the properties of the samples was performed.
