MODAL ANALYSIS OF TITANIUM AND ALUMINIUM ALLOYS HYBRID BEAMS IN VARIOUS TOPOLOGICAL DESIGN
AbstractAdditive manufacturing expected to have a market share of 20 billion dollars in 2020 presents unique design freedom which is not possible with other manufacturing methods. Hence, it’s observed that the applications of titanium and aluminium alloy materials on cellular structures catch more attention day by day because of having low-weight as a result of combining titanium alloy or aluminium alloy and cellular design. In this study, modal analysis of titanium alloy and aluminium alloy hybrid beams in various cellular design like honeycomb with different thickness was conducted by using finite element method (FEM) in order to obtain natural frequencies of these hybrid beams. Furthermore, the shape of beams and displacement vector sum results were recorded during 10 modes in Block Lanczos method in Ansys Apdl modal analysis mode. In conclusion, the effect of rib thickness on vibrational behaviour of titanium alloy and aluminium alloy hybrid beams was reported.
