## 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.
