Experimental and FEM investigation of bending behaviors of S-core sandwich panel composites.

• S-core sandwich panel composites design and manufacturing were done. • Finite element modeling and mechanical tests were performed in three-point bending. • Bending behaviors were compared. Sandwich panel composites have numerous applications in material technology. The sandwich panel composite structure's mechanical behavior and performance are determined by the material properties and geometry of the relevant components. The top and bottom sheets of the designed sandwich panel composite material are made of stainless steel-316, the core material is aluminum 1050A-0, and the binding element is DP-8405 acrylic adhesive. Three-point bending tests and finite element models were utilized to investigate the bending behavior of S-core composite sandwich panels. Finite element models have been developed to characterize the effect of composite element bending behavior on variations. The specific flexural modulus and strength of composite S-core sandwich structures can be compared to core structures in the literature in general. As a consequence, the minimum weight design was used as a guideline to produce weight and density-efficient hybrid composite sandwich panels. The load-carrying capacity of the composite panel increased as the wall thickness of the S-shaped core increased when the damage loads were examined in the variations. It has been ascertained that as the core height increases, the load-carrying capacity of the composite panel decreases. [ABSTRACT FROM AUTHOR]
