===== EvpMixtHHypoMaterial =====
Extension of the mixed hardening framework developed in ''EvpMixtHHypoMaterial'' material to consider .

===== Kinematic hardening models =====
Extension of 

  * ''ArmstrongFrederickKinematicHardening''
  * ''DruckerPragerKinematicHardening''

===== YoshidaUemori02KinematicHardening =====
Nonlinear kinematic hardening adapted from the two-surface developed by [[http://www.sciencedirect.com/science/article/pii/S074964190100050X|Yoshida et al., 2002]]

$$ \dot{X}_{ij}^{yu} = C \left( \dfrac{2}{3}\,a\,D_{ij}^{vp} - \left( \dfrac{\overline{X}_{ij}^{yu}}{\overline{\sigma}} \right)^{\zeta-1}\, \dot{\bar{\varepsilon}}\, X_{ij}^{yu} \right) $$

where $\overline{X}_{yu}^{ij}$ and $\overline{\sigma}$ are the equivalent backstress and the equivalent stress, respectively, which are computed based on the selected yield criterion.

===== Cleaning =====
I have performed a tab cleaning service (~60 files).
