Analysis of Mechanical Behavior of Sandwich Panels

Abstract

AbstractThe structural sandwich can be described as a subgroup of multilayered of structures of composite, modified for the expected lifespan state of loading. A classic structural sandwich is fabricated by embedding the core between the two skins. Due to lighter in weight, a structural sandwich is widely applicable in the engineering fields like aerospace, civil, mechanical, and also in marine. Sandwich structures are gaining more attraction because of their higher strength along with stiffness to weight proportionality as well as the anisotropic characteristics of the sandwich material. Therefore, such structures are being adversely employed for the fabrication of rods, beams as well as columns. However, the rods, columns, and beams are subjected to compression, axial tension, and bending, respectively. Transverse loading is the reason to pronounce the more shear deformation effect in the beams of a sandwich. Therefore, in recent years, the study of buckling, free vibration, and bending of beams of a sandwich is gaining more attention. In the present work, efforts have been made to analyze the fabricated sandwich panel to comprehend the various mechanical behaviors such as stress, strain, free vibration, and bending along with buckling. Strength and deformation characteristics subjected to various loading and boundary conditions have been studied. Moreover, the proposed sandwich structure will be compared with the equivalent conventional structure to know its specific behavior.KeywordsSandwich structureMechanical testEpoxyOrange peelFodderNeat flax fiber mat
