The loading is complex in real life and the delamination is not only occurring in pure modes. Mixed mode delamination is important to be considered in the research. The purpose of this study is to involve the mode ratio participation in the mixed mode I-II-III delamination of carbon/epoxy composite laminate. Theoretical analysis was carried out to determine the mixed mode ratio and theoretical fracture energy for different mode ratios. A finite element model, Model 1 was developed based on the previous 10PBP model proposed. Mesh convergence test was carried out to identify the suitable mesh size and number of element for the model. The loading conditions which are the distance between the loading points are modified to induce different mode ratio to produce Model 2 and Model 3. The finite element result of Model 1 was compared with the previous experimental results and the percentage difference of stiffness value was calculated. Force displacement curve of Model 2 and Model 3 showed the expected trend similar to Model 1. The models were validated and able to simulate the mixed mode I-II-III delamination. Cohesive zone analysis was carried out for all three models to determine the fracture energy, mode ratio and phase angle along the crack front. The results has shown that the entire crack front of the cohesive zone was damaged during the peak load. For Model 1, Model 2 and Model 3, the cohesive zone length was determined to be 1mm, 2mm and 2.5mm respectively. It can be concluded that different mode ratio participation showed slight variation in the delamination behaviour. shafika UTM 92 p.
