Dislocation Dynamics (DD) is a numerical method for studying the evolution of a population of discrete dislocations in an elastic medium under mechanical loads. The pyLabDD package introduces a simple version of Dislocation Dynamics in 2-dimensional space to study fundamental aspects of plastic deformation associated with the motion and mutual interaction of dislocations. Dislocations are considered as pure edge dislocations where the line direction is normal to the considered plane.
Installation
After download and changing the current working directory to the 'trunk' folder of the repository, the pyLabDD package is installed with the following command
$ python -m pip install . --user
After this, the package can by imported with
import pylabdd as dd
The correct implementation can be tested with
$ pytest tests
Documentation
Online documentation for pyLabDD can be found under https://ahartmaier.github.io/pyLabDD/. For offline use, open pyLabDD/docs/index.html to browse through the contents. The documentation is generated using Sphinx.
Jupyter notebooks
pyLabDD is conveniently used with Jupyter notebooks.
Available notebooks with tutorials on the dislocation dynamics method and the Taylor hardening model are contained in the subfolder notebooks
. An
overview on the contents of the notebooks is available here.
The Jupyter notebooks of the pyLabDD tutorials are also available on Binder
Contributions
Contributions to the pyLabDD package are highly welcome, either in form of new notebooks with application examples or tutorials, or in form of new functionalities to the Python code. Furthermore, bug reports or any comments on possible improvements of the code or its documentation are greatly appreciated.
