Hi,
I am working on issue where the Cap cover is made of PP5 material and subjected to thermal loading. I wanted to perform creep analysis of the polypropylene cover. Cover is failing in the field. I have recieved the tested material data from material lab in the form of Tensile Stress Vs Time at different temperatures. Can any expertice please help me to simulate the Creep analysis of the PP5 cover.
Based on the supplier test data of PP polypropylene, I have following queries;
1.    Material Model Selection: Please recommend the most suitable material model for polypropylene(PP5) under creep conditions.
2.    Inputting Experimental Data: Measurement material data is Tensile Stress Vs Time format (MPa Vs sec). How can we input our experimental material data into Abaqus to accurately represent the material's time-dependent behaviour?. 

I am Currently using abaqus 2023.

Thank You
Arun
