NIMS

This Matlab toolbox has been developed to plot and to analyze (nano)indentation data (with conical indenters). Please, have a look at the full online documentation here: http://nims.readthedocs.org/en/latest/

To get started with the NIMS toolbox, clone the repository, then run Matlab, and cd into the folder containing this README file.

You can start the launcher by typing "demo" at the Matlab command prompt.

Features

This Matlab toolbox has been developed to :

• Plot and Analyze nanoindentation dataset with standard deviation ;
• Coefficient of the power law fit of the load-displacement curve ;
• Energy of the loading (area below the load-displacement curve) ;
• Plot of the Stiffness and the Load/Stiffness² evolution ;
• Young's modulus and Hardness of bulk materials ;
• Young's modulus and Hardness of a thin film on a substrate or on a multilayer sample (3 layers on a substrate) ;
• Generation of a Python script for FEM simulation of indentation test on bulk or multilayer sample with ABAQUS 6.12 to ABAQUS 6.14.
