Hello,
I work on the implementation of an implicit capmodell via UMAT.
I read in the handbook, that ABAQUS uses the engineering shear strain (gam = 2 eps). Up to now I am not sure, if I have to incorporate this condition for the plastic part of the material jacobian. So far I uses sigma/eps for the material jacobian and it works very well.
Has anybody some experiences?
Thank you
