A Matlab toolbox to plot and to analyze nanoindentation data (with conical indenters)

nims's Issues

Show specimen name in the GUI (title ? legend ?)

Automatic detection of units for load, disp and stiffness ?

Add visco elastic properties extraction into the GUI

Incertitude to plot along x-axis (SD on displacement...).

CSM correction to check

CSM correction from O&P in Matlab_Code to check ==> See file "CSM_correction.m"

Add popup menu to set units for load and displacement if not standard

List with multi-selection instead of popupmenu for the elastic models

... for a multi-plots on the same graphic

Check calculations (NaN or complex numbers...)... introducing errors for the plots !

... or clean raw data (e.g. : remove all values below 5nm of displacment) ?

Running issue

Dear David,
I try to run the code that I have downloaded on 05.06.2020 on a MATLAB version R2019b.
But it does not work (I see glimpses of the H and E map but then they disappear).
I have used your code on the same MATLAB version before with no issues.
Could it be the new downloaded TriDiMap version?
Best regards,
Asef

Plot of film hardness vs sample hardness... ?

Documentation to finish (hardness for thin film, multilayer models...)

Film Thickness in FEA Python Script and Abaqus in different

Hi David,

I have noticed in tutorials/examples included in NIMS is that it does not return layer thickness what we put in MATLAB GUI e.g If put t1=200nm , t0=1500 and rest is the substrate and generates python script. When I visualize results in Abaqus it appears that film thickness are changed. Could you please have a look at it. I have tried to replace T0 and T1 but it does help. Please see below Images.

Kind Regards,

Qamar

Extract automatically only loading part from indentation results...

Indentation area definition from AFM measurement

Difference from Ad and Ap in Gwyddion... Look into the source code.
https://sourceforge.net/p/gwyddion/discussion/general/thread/19dbd1823b/

Get the angle between the normale to the surface and the z axis. Then when angle is lower than 90°-65.3° = 24.7°, it is not the residual imprint from a Berkovich tip for example.
Add details in the doc.

Implementation of Kao's model

Need to define hardness substrate and hardness values for thin films... into the GUI
... and add Kao's model into the GUI (only in the repo right now)...

Error using Conical Indenter data

Hi David,

I am using Sphero conical indenter but when I chose indenter as Conical in GUI it generates python code but gives an error in Abaqus, sees be; low image. Could you please have a look at it.

Could you please also let me know how to define indentation depth as by default it goes -200nm Deep in the surface.
I am using 10um Sphero conical indenter, could you please let how can I put the radius in GUI.
