Robert Caulk proposed the following answer:
Hello,

>>Yes,I know it,but I have no idea about how to know the stop
condition.Could you please give me some advice or reference.

I guess this depends on what you want to study...if you are trying to
study the strain-softening phase then you'd need different stop logic
than if you are only interested in the yield strength. Yield strength,
look for when deviatoric stress is less than XX% of max historical
stress. Strain softening, look for a max strain value to decide when to
stop.

>>As for my curve, I've run the script 1e8 iter so far,the stress-strain
curve fluctuates all the time,and the stress is between 4e6 to 5.8e6...
It seems that there is no damage to the sample?

So there is no linear increase in stress before stabilizing? Sounds like
the simulation is not stable. Plot unbalanced force to confirm.

Cheers,

Robert
