fatigue crack propagation

Hi, I'm trying to perform a supposedly-simple experiment on fatigue crack propagation of UHMWPE. I use a compact-tension specimen on a servopulser hidraulic testing machine. I will try to do the experiment on a fix Pmax with a varied force ratio (R) from 0.1 to 0.5. I'm having trouble in deciding the maximum force Pmax. How does one decide the amount of force applied for FCP testing? Calculation steps and so on.

criterion

Dear all,

my problem is dealing with a fatigue crack propagation analysis using XFEM (linear elastic case) with a prescribed initial imperfection in the modeled solid. What is the criterion to exit from such a kind of analysis?

Thank you in acvance!
