Design and analysis of thin walled composite beam

Abstract

In present research composite beam of Glass/Epoxy has been taken for the analysis of failure bending moment by Finite Element Analysis. The orientation of the plies are oriented as [0°/-45°/45°/90°/90°/45°/-45°/0°] named as S1 are tested and analyzed with the Tsai- Wu failure criteria. It is found that the sample S1 composite having low load carrying capacity and bending moment. Furthermore, another ply are oriented as [0°/90°/0°/90°/90°/0°/90°/0°] named as S4 are tested and analyzed Tsai-Wu failure criteria under same loading condition. It is found that the sample S4 composite having higher load carrying capacity and bending moment. The composite materials such as the Graphite/Epoxy and the Boron/Epoxy have also been considered for the analysis with the same boundary condition as the Glass/Epoxy. Comparative result shows that the Boron/Epoxy having highest load carrying capacity and bending moment as compare to the Graphite/Epoxy and the Glass/Epoxy. The results obtained from the proposed method having good agreement with the results obtained from the previous research.
