First of all, download the source code of the Matlab toolbox.
To have more details about the use of the toolbox, please have a look to :
How to use the GUI for indentation data analysis ?¶
First of all a GUI is a Graphical User Interface.
- Create or update your personal YAML config. file stored in the YAML folder
- Run the following Matlab script :
- Answer ‘y’ or ‘yes’ (or press ‘Enter’) to add path to the Matlab search paths, using this script:
- The following window opens:
- Import your (nano)indentation results, by clicking on the button ‘Select file’. Click here to have more details about valid format of data.
- A load-displacement curve is plotted (with a power law fit). The loading work is also given in the title of the plot.
- It is possible to plot the stiffness (raw data) without setting the GUI for Young’s modulus calculation.
- Choose and set (if needed) the indenter used to obtain (nano)indentation data.
- Select the lowest and the highest depth values (optional).
- Set the CSM correction (Berkovich indenter only !) (optional).
- Set the number of layers of your sample (0 = only bulk material, 1/2/3 = 1 to 3 thin layers on a substrate) (see Figure 5).
- Set the thickness, the Poisson’s coefficient and the Young’s modulus to each layer.
- Select the model to use for the contact displacement calculation and select the correction to apply.
- Select ‘Red. Young’s modulus(film+sub)’ or ‘Red. Young’s modulus(film)’ in order to plot the evolution of the reduced Young’s modulus (raw calculation) of the sample vs. the evolution of the reduced Young’s modulus (modeled) of the sample and/or of the thin film.
- Select the analytical bilayer or the multilayer model to use for the modelling of the reduced Young’s modulus of the top thin film.
- Press the button ‘SAVE’ and a YAML results file and a picture of the figure (.png format) are created and stored in the following folder.
- Press the button ‘FEM’ and generate a Python script to model nanoindentation of multilayer sample based on parameters used in the GUI for ABAQUS.
