Hi, I am planning to conduct Split Hopkinson Pressure Bar experiment on a certain material to obtain stress-strain plot under high strain rates.
As for my material model, I am using Drucker Prager plasticity and Shear damage.
Right now, I am planning to extract fracture strain data(for shear damage) from stress-strain plot under different strain rate.
I have read several papers on SHPB experiment but I still wonder,
What other kinds of parameters/results I can extract from this experiment in order to improve my material model?
For example, for drucker prager hardening, damage evolution from shear damage etc
Thank you.

Even material properties that don’t have physical interpretation and can’t be measured in experiments (like some constants for damage/failure), may be calibrated using experimental results. You can perform both physical and virtual (numerical) version of SHPB and then adjust the material model in Abaqus so that it matches the results of the physical test.
 
Noted, Thank you very much FEA Way!
