Numerical Analysis of Aluminium Cellular Beams with Cells of Different Diameters

Abstract:

The paper presents a numerical analysis of aluminium cellular beams. The ADINA System based on the Finite Element Method (FEM) is used for the calculations. The beams made of 6061-T6 aluminium alloy are analysed. Such beams are used in civil engineering and aircrafts industry as the load-bearing parts. The beam components are joined by Refill Friction Stir Spot Welding (RFSSW). The I-profile beams with cells of different diameters, i.e. 62, 72 and 82 mm, in the webs are analysed. In each case, cell arrangement in the beam is the same. The bending of the fixed-end beams with concentrated load is analysed. Extreme values of the displacement for the beams material and RFSSW joints are emphasized. The effective stresses for the beams and FSSW joints are calculated. Normal stresses in the top flanges, bottom flanges and webs are given.
