Analysis and Comparison of Two Composite Beams by Finite Element Method

Khan Shifa Khanam

Abstract


For two beams of composite material an analysis using finite element method (FEM) is done to obtain results for stresses, and deformations in different directions. For each beam same aspect ratios are considered and different composite material layer patterns are used for each beam. The tool used for analysis based on FEM is ANSYS workbench. Comparison of the results is done for both the beams with respect to each other. For first beam the layering of the composite material layers is done such that one type of composite material is inserted between two layers of another composite material. While for the second beam all the layers are of the same composite material. Cross section of the beams being hollow circular and are subjected to fixed supports at both ends.
