Dear All,

I'm working on a decohesion problem owed to initial stresses using the Adhesion node ( Contact Zone model implementation )

I have generally set up a working model although I would like to start extracting some useful information out of it now.

I'm looking for a way to extract the crack propagation length of my interface. I have tried picking out the maximum and minimum of solid.gap using maxop1(solid.gap,r) ( axis symmetric model) and minop1 accordingly. The issue is that as my geometry scales the evaluation of the minimum gap (however I try to extract either by the preset contact options or by a coupling operator ) gives position either too close to the edge or at 0, which at leas is not what I see in the surface plots.

Essentially I need a way to find the location where contact is lost for the first time for each simulation.

Any ideas ?

Thanks in advance!
