Developing an ANSYS Creep Model for Polypropolene from Experimental Data

This paper describes a procedure for modeling the primary creep behavior for one of the most widely used commodity resins, polypropylene. The procedure involves using ANSYS to verify an assumed mathematical creep model and calculated creep behavior material properties. ANSYS results are compared to both creep and stress relaxation experimental data and then calibrated to give a good correlation to the response of this particular grade of polypropylene.
