## How to use the GUI for “pop-in” analysis from indentation tests ?¶

First of all a GUI is a Graphical User Interface.

• Run the following Matlab script and answer ‘y’ or ‘yes’ to add path to the Matlab search paths :
path_management.m

• Then, run the following Matlab script :
demo.m

• The following window opens:

Screenshot of the main window of the PopIn toolbox.

• Import your (nano)indentation results (.xls file obtained from MTS software with at least more than 20 indentation tests for statistics), by pressing the button ‘Select file’.
• Select the end segment (if segments exist), in order to set the maximum indentation depth.
• It is possible to plot the stiffness (raw data) without setting the GUI for Young’s modulus calculation.
• A picture of the main window as .png file is created and Weibull data are stored in a .txt file when you press the button ‘SAVE’.
• Results are accessible by typing in the Matlab command window (here for 50 indentation tests) :
gui = guidata(gcf)

gui =
config: [1x1 struct]     % config. of the GUI
handles: [1x1 struct]    % handles of the GUI = buttons, boxes...
flag: [1x1 struct]       % flags for errors, calculations
data: [1x50 struct]      % data cropped
data_xls: [1x1 struct]   % details about .xls file
settings: [1x1 struct]   % settings for calculations
results: [50x1 struct]   % results obtained after calculations
Weibull: [1x1 struct]    % Weibull fit results
