DAMASK_EICMD

This is a DAMASK fork with implementation of the "Discrete Deformation Twinning Model" based on work done by Dr. Satyapriya Gupta and Dr. Philip Eisenlohr at MSU.

The Discrete Deformation Twinning Model

The aim of this model is to accurately match experimental observations of deformation twinning while remaining computationally efficient compared to physics-based phase field models.

• We introduce stochasticity for the nucleation and growth events of twinning through random sampling, similar to Monte Carlo Methods.
• The ease or difficulty of a twinning event is controlled by adjusting the frequency of sampling.
• At each voxel, the state of twinning is treated as a discrete quantity, unlike the approach based on diffused volume fraction method.
• The kinetics of twinning occur in the form of a “jump,” rather than following a rate equation as in the “pseudo-slip” approach.
• The jumped state is evaluated using the correspondence matrix from Niewczas, Acta Materialia, 2010.

Repository Locations

git.damask.mpie.de

All code development is centralized in the principal DAMASK code repository hosted at git.damask.mpie.de. Access to this GitLab instance requires registration and is granted to anyone with an interest in actively supporting the development of DAMASK.

github.com

GitHub hosts the publicly accessible, but read-only, mirror of the principal DAMASK code repository and replicates its three top-level branches from git.damask.mpie.de.

The site is primarily meant to provide a forum for Discussions and Issues.
