Why only Simple tension based Stress relaxation/ Creep / Strain rate test data are used for visco-elastic material characterization?

In general, to characterize the time-dependent (Visco-elastic) properties of filled- rubbers, different tests such as stress relaxation/ creep/ strain-rate sensitivity are carried out in "simple...
