Modeling a fluoropolymer seal that is part of a threaded connection can be a challenging problem due to the complex geometry and the viscoplastic properties of the polymer seal.
Here is a presentation that I created that illustrates one way to perform this type of FE model.
Version 6.4.0 of PolyUMod includes 2 advanced UCREEPNETWORK and VUCREEPNETWORK models that can be used with the Abaqus PRF model.
Tutorial on how to simulate the large-strain temperature-dependent response of thermoplastics through the glass transition temperature (Tg).
This article examines different material models for polyetherimide (PEI), and finds the most accurate model for FEA use.
