The objective of this project is to investigate the bending response of composite I-beam structure using Finite Element Analysis (FEA). Two types of I-beams with different ply thickness were modelled “4Ply Control” and “8Ply Control”. Material such as Carbon Fibre and Toray T700 were applied for both types of I-beams. Thereafter, FEA was performed to simulate the structure bending response of composite I-beams under static structural analysis using ANSYS Workbench. The concept of how the load will be applied to the I-beam were obtained from previous Final Year Project (FYP). The I-beams were tested experimentally using the method of Three-point bending. Therefore, ANSYS simulations were carried out as it was not carried out previously. Convergence of results were conducted on the finite element model to ensure that all subsequent finite element results extracted are converged. The results obtained from ANSYS were then compared against the results obtained from previous experimental study. It was found out that Toray T700 material in ANSYS experience higher force applied as compared to experimental study in term of deformation the I-beams to the prescribed deflection. This could be due to support ends of the specimens were not allowed to rotate in ANSYS which contradict the response of the test specimen in experimental study. It was also found out that I-beam modelled using Carbon Fibre and Toray T700 will experience different force applied in order to deform the I-beam due to difference in material property. Convergence study has also been carried out.
