Need help on Creep Analysis

Hi Everybody,


I need to conduct Creep Analysis of plastic components 33% glass fiber with nylon 6/66. The material is from the DuPont.


The component needs Creep Analysis check, as these are tested from -40 degree Celsius to 150 Degree Celsius. It has an internal operating pressure of 120 psi.


Kindly let me know how to go with it and what all material data do I require. Also how to find/calculate creep constants for the analysis.


Presently I am having material data which gives me tensile stress from -40C to 150C at different strain levels (0.1% to 3%). Can I calculate C1, C2 and C3 from this data.


Please let me know what more data I require.


Best Regards
