Indentation stress-based models to predict fracture properties of brittle thin film on a ductile substrate

In the present work, nano-indentation experiments were performed on the surface of alumina film and diamond-like carbon (DLC) film on PEEK substrates using an axisymmetric indenter. After indentation, ring cracks were noticed in the film by scanning electron microscope. Stress analysis results indic...
