Viscoelastic material model in abaqus-am i taking the correvt approach

Hi all,

I have been trying to gain an understanding of representing a viscoelastic material in abaqus. To do this i have been trying to represent polypropylene using data obtained from creep curves found in literature (attached). To now what i have been doing is the following: Note i am using Abaqus 6.7

In material manager: selecting Elastic-inputting Instantaneous Youngs Modulus, E, Poissons, v, (E=1.8GPa, v=0.4) and setting the moduli time scale to instantaneous. And Viscoelastic-Domain:Time, Time=Creep Test data and inputting Shear Test Data
