Cyclical Nanoindentation Stress-Strain Measurement

The Stress-Strain curve obtained by Nanoindentation reveals the correlation of "Stress" and"Strain" of a given material under nano controlled loads. Unlike the traditional Tensile Testing method of obtaining Stress-Strain curve data, which gives data at a macro level, the Nanoindentation method provides vital Stress-Strain curve data at nano level scale without the large and intense machinery. The Stress-Strain curve of various materials will vary widely. Ultimately, the Stress-Strain curve provides crucial information on the threshold between elastic and plastic-elastic behavior zone as the sample is subject to increasing loads.
