Selection of Core for All Steel Sandwich Panel

Sandwich panels can be used for various applications. Many a times aim of the designer is to design panel at which can carry load at min weight and cost. Sandwich panels can be effectively used in such case. Design of facing and core is an important aspect for sandwich panel. Various types of materials like steel, aluminum, composites can be used, among which structural steel is a cost effective material. Various designs are possible for all steel sandwich panel, using various types of core. Standard cores using Z-sections, tubular sections, hollow square and rectangular sections, angle sections, C-sections, I- sections etc. can be used. Such sections are readily available also produce fairly accurate panel at reasonable cost. Special types of core like corrugated core, honeycomb core can also be used. Generally corrugated& honeycomb core produce lightest panel but cost of manufacturing will increase substantially. In this paper, we have analyzed all steel sandwich panel having different types of cores using ANSYS. Core size is selected in a manner such that weights of the panel are nearly same this helps in comparison of data. We have analyzed the models in ANSYS for bending load and find out best design among which gives best lowest equivalent stress& deformation.
