Finite element Analysis of Honeycomb filled Metallic Tubes Subjected to Axial Loading

A comprehensive study of buckling behavior of polygonal tubes with honeycomb filler under axial loading is presented in this paper. Honeycomb filled tubes have got a lot more attention due to their strong and stiff behavior with enhanced energy absorption capacity. For simulating the buckling behavior events of finite element models eigen value buckling code was used using the Abaqus/Explicit. This paper firstly investigates the buckling behavior of polygonal tubes without honeycomb filler and then the antipodal with honeycomb filler. The calculated buckling response of polygonal tubes is shown to better resembled when honeycomb filler is used.
