Abstract
Finite element analysis (FEA) is one of the most widely used techniques in predicting the material behavior under loading conditions in various applications e.g., thin film coating. Thin film coating offers superior mechanical characteristics such as hardness, resistance to wear, etc. In this study, the finite element analysis method is used along with the Johnson Cook Plasticity Model to obtain the deformation behavior and stress distribution of TiN-coated thin film sample. Material properties of TiN thin film coating obtained through nanoindentation are the inputs for the material model. Berkovich indenter is modelled to simulate the results. Elastoplastic analysis is done under different strain conditions as per the Johnson Cook Plasticity Model. FEA model results obtained are compared with the reported results. There is a close match between the values of material model 6 and experiment 1 which suggests that FEA is a prominent tool in predicting the nanoindentation results.
