Hi,

I'm doing an Explicit Dynamics simulation regarding impact resistance of a ceramic laminate. I'd like to determine the maximum load (e.q. maximum drop height of a standardized sphere) before material failure.

I'm using the Principal Stress Failure criterion, as this is obtainable experimentally. Extrapolation, however, messes with my result stresses at the crack tips. I'd like to suppress that. Further, it would be great if I could do a multi-step analysis, where the load is adjusted according to the last cycles results, e.g. whether material failure occurred or not.

I seem to be unable to insert the necessary Command-Objects, as their icon is greyed out. I have tried using snippets, however I'm unsure how they need to be structured. They look like a python script, however I don't know how exactly one calls a function for example.

Any tips regarding integration of commands are much obliged.

Thanks in advance
