Huang's UMAT; Crystal Plasticity; Cyclic Loading; Bauschinger effect

Hello,  

In the Crystal Plascticity UMAT model for Abaqus (by prof. Hunag) the Bauschinger effect which is important for cyclic loading, is not considered.  

Is there any edited version of this UMAT considering this effect for cyclic loading (by also considering kinematic hardening)?

Kind regards,

Omid
