The title basically sums it up, how do I extract the disbond time for the nodes so I can plot crack growth vs. number of cycles? I have the example file as well as my own models (dcb fatigue) and run into the same problem, so clearly I am missing something in the procedure, but I don't know what.
For a quasi-static analysis, it is reasonably easy: output dbt, define the path along the bondline, extract the data (and relate it to the applied load). However, when I do this using the direct cyclic approach (but instead relate to cycle number instead of load), the disbond time for every node reports the time as "2" which is the end of one cycle (step 1 is the initialization step, step 2 is the cyclic analysis). I can extract the numbers manually by going frame to frame in the direct cyclic step, and there I can see the actual step time and bond state of the nodes, so I know the information is there, but I really don't want to extract the data this way though, as it would take forever.
