Nanoindentation is a variety of indentation hardness tests applied to small volumes. Indentation is perhaps the most commonly applied means of testing the mechanical properties of materials.The nanoindentation technique was developed in the mid-1970s to measure the hardness of small volumes of material.or nanoindentation experiments performed with a conical indenter on a thin film deposited on a substrate or on a multilayer sample, the NIMS Matlab toolbox is useful for load-displacement curves analysis and calculations of Young's modulus and hardness of the coating.
