Thanks Jorgen.

Hi Jorgen,

I am having a little trouble interpreting this data. Just now I am looking at PTFE tension_cyclic in word (won't open in excel). Firstly, should I be opening in a different program? If...

Hi,

I am trying to generate a model for applications where a polymer (such as ETFE, FEP, PTFE) is subject to different strains. Most empirical fatigue models are based on stress amplitude...

Hi,

Just a quick modelling question. I am FEA modelling a grade of polyurethane but I am only interested in strains as high as about 10-15% tension. Since these strains are relatively small can a...

I use COMSOL FE-software. Out of interest, how do you define damage, D? I'm guessing it's a function of cyclic strain and number of cycles? Do you have a reference?

Hi,

I think the theory you have got there is fine. However...

I ran a project doing something similar (but different) to do with materials at temperature. One problem with this was with the...

Hi,

I am fairly new to this type of analysis and before I get to the fatigue part have an FEA model to deal with first! I am looking to do this with various grades of PTFE, ETFE etc.

But my...
