TriDiMap Matlab toolbox

_images/icon_tridimap.png

Determination of the mechanical properties of each individual phase in the case of a multiphase, heterogeneous or composite material can be achieved using the grid nanoindentation technique [1], [2] and [3].

The TriDiMap toolbox has been developed to plot, to map and to analyze (nano)indentation dataset.

With this Matlab toolbox, it is possible:
  • to map (in 2D or 3D), to interpolate and to smooth indentation map;
  • to plot elastic modulus vs hardness values;
  • to plot and to fit probability density functions;
  • to plot and to fit cumulative density functions;
  • to extract statistical values (mean, min, max with standard deviations) of mechanical properties and fractions for each phase;
  • to correct mechanical map using image correlation with microstructural map;
  • to correlate/compare mechanical map with microstructural map;
  • to plot 4D mechanical property map (indentation tomography).
