Hi all, we (University of California, Merced) have been working on this chassis for a long time now and cannot get any further with the analysis.
If we cannot get this working in a couple days, then we will have to scrap this chassis for our project so if anyone could help us out, we would greatly appreciate it.
In the model, I have only included the inner skin. The outer skin was removed for simplicity. And I don't even want to think about how to model and analyze the Laminate Core...
I have tried using the soft relief function, contact sets, different ways of modeling the chassis, and etc with no avail.
For now we would like to fix the rear of the chassis and apply a 1000lb load normal to the front face of the front bulkhead.
