Nanoindentation was done on HAp based on an Oliver and Pharr power law . It has been used to assess the stiffness of soft biomaterials such as the uterus, kidney, liver, and spleen, as diseases cause variations in stiffness in some organs. The Hertzian, JKR, and Oliver & Pharr models were used in the analysis [37] and a hybrid computational-experimental technique was developed, Nanoindentation was also performed on Filtek Z350 XT, which is a dental nanocomposite reinforced with nanoparticles . Nanoindentation was done on HA-coated Mg alloys, which are used to stabilize bone fractures [39-42]. Atomistic, crystalline, and surface chemistry are the areas on which the computational studies of bioceramics are focussed, some of which have been discussed here [43, 44].
