How to pass the plastic strain components to ABAQUS subroutines?

Is there any way to pass the plastic strain components to ABAQUS subroutines, e.g. VUHARD? I'm wondering whether I could write a subroutine to calculate the equivalent plastic strain directly from plastic strain components. 

I'm working on a dynamic simulation using ABAQUS/Explicit. The material is under a high-frequency loading and unloading, and large deformation is expected. 

ABAQUS calculate the equivalent plastic strain in the rate form, which returned me an outrageous PEEQ value. Ironically, all the PE components seem correct.  

My issue would be solved, if I could write a subroutine to calculate the equivalent plastic strain directly from plastic strain components. 

Thank you very much!

I am not sure how are you gonna to calculate the Effective from the principle plastic strain component, as this is what already Abaqus do in my opinion.

My understanding is that the effective Plastic strain is considered the other strain components, in another word, is more efficient if you have multiaxial load than uniaxial at the point of interest.
