Modelling of Honeycomb Sandwich Structure with Curved Edges and Performing Analysis Using Finite Element Method

Abstract

The aim of the study is to perform FE Analysis using ANSYS for the Honeycomb sandwich structures with varying skin thickness ranging from 0.5 to 2 mm and edges of the honeycombs are converted into curve shapes to avoid any stress concentration at the intersection. The study of the natural frequencies of the structure is also carried out. The core structure is made up of Aluminum alloy and the skin or face sheet is made up of carbon fiber and the properties are been evaluated from ANSYS Engineering Data Source. The core has been modeled with a radius of curvature of 1.5 mm and different from conventional honeycomb structure with sharp edges, an increase in skin thickness has improved the load bearing capacity of the specimen.
