My research mate Fernando Coelho came up with this excellent terminology regarding a novel publication about using mechanical pull-off testing for failure pattern analysis for adhesives. This is already standardized via ISO 10365.
However, it is important to note that even 40 years ago, Hutchinson and Sue (1992) already applied fracture analysis tests correctly to address this issue - and not pull-off tests.
What do you think about this issue?
Is it correct to use simple pull-off testing for fracture analysis?
Let me know in the comments below!

The variation in analysis is so great that just about any model will work. The question (problem) is applying to say an acceptance tests with documented uncertainty for the values determined.
Edward Vojcak , thanks for sharing.
Interesting point. The variation is so great that results may look right.
However, I think that this is mixing up computed tomography results with magnetic resonance tomography.
So, pull-off test does not belong to fracture mechanics no matter you can create fracture patterns.
