Examples of nanoindentation data

Warning

Only square or rectangular indentation grids can be loaded into the Matlab toolbox.

Warning

Only .xls or .xlsx file can be loaded into the Matlab toolbox. Or Matlab code has to be updated. See the section ‘New results file’ below.

Note

For 2D maps, only a sheet with average values at a given indentation depth is enough. But for a 3D mapping, sheet with mechanical properties as a function of indentation depth are required.

File examples from ‘MTS/Agilent’

For a 2D map: MTS_example1_25x25.xls

For a 3D map: MTS_example3_5x5_testSlice.xlsx

File example from ‘Hysitron’

For a 2D map: Hysitron_example_10x10.xlsx

File example from ‘ASMEC’

For a 2D map: ASMEC_example_20x11.xlsx

File example after crop and interpolation steps

For a 2D map: MTS_example1_25x25.xls_interp_81x81.xls Don’t forget to set ‘Agilent’ for the equipment, when you load an .xls file generated using the TriDiMap GUI.

New results file

In case of other or new experimental results file, the most important is to know the pattern of the indentation grid. For example, the following figure shows the pattern of a typical indentation grid obtained using the software (e.g. Testworks…) of MTS/Agilent.

The Matlab function to modify to load specific indentation results file is: TriDiMap_loadingAllTests.m
