Bending Analysis of Sandwich Panel with Soft Core

Abstract

A sandwich panel is a lightweight structure, economical and having low thermal conductivity. It is made up of three layers in which the middle layer is called core which is bounded with thin layers at top and bottom called faces. Generally, the core has relatively low-density which makes it lightweight. The bending behavior of the sandwich panel with soft core is studied using the finite element (FE) based software ABAQUS. Shell elements in the three-layer arrangement has been considered to model the sandwich panel. The present model is validated with suitable published results. Then it is extended to analyze bending of sandwich panel with soft core. An FE model has been developed to generate many new results for different thickness, boundary conditions, aspect ratio, etc.
