Two different models (2-zone and 3-zone) for describing the deformation and fracture behavior of tearing ligament was compared and discussed based on the experimental results made by Kim et al. The models are based on the Essential Work of Fracture approach for predicting the specific total work of fracture along the tear path across plastic zones. The experiment and analysis were based on 2-leg trousers tear specimen. The materials chosen in this work were PET (0.508 mm). The results showed that the accuracy of 3-zone model was higher than 2-zone model. It was found that this difference is because the 2-zone model did not consider the plastic deformation caused by loading prior to tearing. Also a finite element model was created to simulate the behavior around the crack tip.
