<EIGENSTRAIN> beta#

Description#

This object class provides the eigenstrain models in general TFA framework. It is used to define the evolution law of the “eigenstrain” which is the strain measure of mismatch between phase locations:

(617)#\[\boldsymbol{\dot \beta}_r = \boldsymbol{\dot \epsilon}^p_r - D (\boldsymbol{\beta}_r - \omega \boldsymbol{\epsilon}^p_r) || \boldsymbol{\dot \epsilon}^p_r ||\]
(618)#\[\boldsymbol{\dot \xi}_r = - D (\boldsymbol{\xi}_r + (1 - \omega) \boldsymbol{\epsilon}^p_r) || \boldsymbol{\dot \epsilon}^p_r ||\]
