Calibration of rate independent phenomenological plasticity models

I have a question regarding the experimental determination of rate independent phenomenological elaso plastic constitutive model.

Since the models are rate independent, does the strain rate in the experiments used to calibrate the model parametes have any influence on the model. I am talking about this in context to the Cap plasticity model used in Abaqus. One has to run a certain number of powder compaction experiments to calibrate the model.
