No problem at all.
Yes, for the Barlat model you can input C and P which are the coefficients of Cowper-Symond's equation to scale the reference hardening (stress-strain) curve at different strain rates. It is sometimes easier to directly input the stress-strain curves (from physical experiments, for example), but if you have the C and P coefficients available, you can use the Cowper-Symond's method as well.
