Is it possible to determine if a sample deforms plastically or elastically from a stress relaxation test?

I performed stress relaxation test, resulting in collecting time, stress, strain. I fitted these data to a 3-decay exponential decay model strain(t)=A0+Ai*exp(-t/ti), with i=1,2,3 and got my...
