Mechanical behavior analysis of functionally graded composite sandwich beams using 2D refined theory

This study aims to examine the influence of geometric and mechanical properties on the bending behavior of supported FG sandwich beams, utilizing a refined shear deformation theory. The material properties are assumed to vary gradually and continuously according to a power-law distribution based on the volume fractions of the constituent materials. By applying the developed analytical model and the Navier solution technique, numerical results for non-dimensional stresses and displacements are computed and compared with those derived from other 2D theories. Furthermore, the proposed analytical model is well-suited for analyzing the static deflection of supported FG sandwich beams subjected to high mechanical loads, making it directly applicable to advanced engineering fields such as aerospace, automotive, and civil engineering, thereby enhancing the practicality of the research.
