POST code for second order elastic constant

Online Help (Under writing)

(Here is a brief video tutorial, and here is an unfinished manual [in Chinese])

• From source code

  MATLAB required

  Two ways:

  • add the path containing the src into your MATLAB PATH

  • Set the src folder as the current folder, then run EPOST_INSTALL (need run MATLAB as administrator)

• From exe file

  MATLAB runtime required. (free but about 2.5Gb)

  Run ElasticPOST_GUI.exe in the bin folder. Note: MATLAB Runtime is required. The code can download and install it for you. (About 2.5Gb)

ElasticPOST is an open source academic free software It is design for post processing of the elastic stiffness matrix

1. For 3D materials in any symmetry, supporting the elastic anisotropy of bulk modulus, Young's modulus, shear modulus, Poisson's ratio and hardness in 3D;
2. For 2D materials in any symmetry, supporting the elastic anisotropy of Young's modulus, shear modulus and Poisson's ratio;
3. Supporting *.xlsx, *.xls, *.txt, *.dat and *.mat data format;
4. Supporting Voigt-Reuss-Hill approximation to average the elastic modulus;
5. Supply some useful tools for 3D figures, such as slice and view point;
6. Supporting *.tif, *.jpg, *.emf, *.eps, *pdf, *.fig figure format;
7. Supporting Windows and Linux system;
8. It will give some tips for errors.
