The plot that you have given indicates one or both of the following:
1) The initial elastic moduli are different for your implementation vs the built-in model
2) The strain rates are different for the two models (your implementation uses a larger strain rate)
One way to check the values is to plug-in value of plastic strain, strain rate, and temperature and to calculate what the expected yield stress is from either model.

Thank you, professor.
Thank you, professor. Apparently, the problem was pretty straightforward pertaining to the use of wrong variable names.
