MCREEP

MCREEP package fits various pre-defined models to creep data.

The package can process both tensile and indentation creep measuremenents
in such a way that the results from the two methods are comparable.

• The creep data:
  • A text file with two columns.
  • The 1st column = time, the 2nd column = deformation.
  • Deformation = strain (for tensile) or penetration depth (for indentation).
• The pre-defined models within the pagkage are:
  • Simple empirical models = Power law, Nutting’s law.
  • Phenomenological models = elasto-visco-plastic models = EVP models.
• The theory and models are described in the open-acces publication:
  • Materials 16 (2023) 834. https://doi.org/10.3390/ma16020834
  • If you use MCREEP in your research, please cite the publication above.

Quick start

1. Install MCREEP: pip install mcreep
2. Download the demo package, unzip it, and follow the instructions in readme file.
3. Basically, you just run the unzipped PY-script and see the results.
   • The PY-script should run anywhere, but the recommended environment is Spyder.
   • The output (in Spyder) should look like in this PrintScreen.

Installation, documentation and examples

• MCREEP is available at PyPI ⇒ installation: pip install mcreep
• Home page of the project is at GitHub and GitHub pages.
• Docs and examples are summarized at GitHub pages.
• All modules, classes and functions are documented by docstrings.
• Full documentation was auto-generated from docstrings by PDoc.

Versions of MCREEP

• Version 1.0 = finalized, working for both tensile and indentation creep
• Version 1.1 = a few important improvements, better documentation
