Abstract: This thesis presents an integrated FE analysis approach of low-velocity impact and CAI test on CFRP laminates. The research is conducted in three stages. Firstly, a FE model is built for the prediction of the severity of low-velocity impact damage. Parametric studies in which the influence of variables such as the thickness and the stacking sequence of the CFRP laminates on the impact damage patterns and severity is investigated. Secondly, FE models with pre-included damage of varying complexity are built in order to study residual CAI strength predictions. Several types and sizes of impact damage such as delaminations and matrix cracks are pre-included, and the effect of the types and sizes of damage on the resultant CAI strength is investigated. In the final stage of this research, the integrated FE simulation is devised. The reliability of the FE simulations are verified by comparison with various experimental results reported in literature.
