I am having some interesting results for the convergence of stresses in an assembly modeled with shell elements.
Roughly speaking, the model is constructed as follows:
The model has a remote load applied to one component. Both bonded and no penetration contacts are used to link individual components. The model is fully constrained with the combination of component contacts and a fixed support applied to a face of one of the components.
The convergence results are interesting for two reasons:
1. Stresses seem to decrease as mesh size is increased.
2. Some oscillation in stress is evident as mesh size is increased.
Any thoughts on what might be causing this response?
Convergence Data is attached.
Thanks,
