pipes equivalence in fatigue tests

[TeeAr]

Hi there !

hope everything is fine !
Please, I am contacting you for following issue.
In the past I have utilized a pipe of copper having diameter D and thickness t.
It has been under a vibrational fatigue test and has passed the test.

I have then changed the pipe.
The new one has got a smaller diameter, let's call D1, and smaller thickness, let's call it t1.

this second tube has not passed the vibrational fatigue test.

I am here asking you if exists a formula that may help me to compare the two pipes for a fatigue test, so that I can determine the suitable thickness t1'

many thanks
