| Abstract Scope |
This paper deals with evaluation of interfacial failure characteristics of an epoxy based adhesive and its predictive simulation by using the finite element method (FEM). To identify the failure characteristics, the T-peel and the in-plane shear tests were designed to obtain interfacial properties in Mode I and Mode II, respectively. The T-peel and the lap-shear joint specimens were prepared with aluminum alloy sheets as the adherend. Thickness of the adherend and the adhesive were 300 and 100 μm, respectively. Tests were then carried out with the specimens to evaluate interfacial failure behavior. For the FE simulation, the cohesive zone model (CZM) was employed to characterize the interfacial failure in Mode I, Mode II, and Mixed-Mode. The FE models were constructed to predict the interfacial failure based on the ABAQUS implicit solver. The FE model predicts the experiments well with a good agreement for both Mode I and II. |
