Hey guys,
i am currently simulating crack growth and Propagation Analysis on on a coated substrate during an indendation process via XFEM. I am not only interested in the initial crack, but rather in the whole cracking process during the complete simulation. To my understanding, multiple cracks will only propagate, after the XFEM enriched feature is seprated by one crack or if multiple cracks emerge during the same time increment. Now my idea was to create multiple partitions with multiple XFEM enriched zones.
My question now is: If a crack propagates through material and reaches another partition with the same XFEM parameters applied, does the crack initiation criterion (in my case MaxPs) need to be fullfilled once again or does the crack just propagate through the second partition normally using the Evolution criterion?
Thank you very much in advance
