Sorry for the confusion, my FEA vocabulary is still developing. I should have said for increased mesh density, i.e. smaller elements, stresses decrease. In the attached spreadsheet I show von Mises stress probed from a point on the end of a strategically placed split line. I get the same...

In my case the stress is decreasing with increased mesh size. Can this behavior also be attributed to singularities?

Noticed an error in the spread sheet... The % element/node differnece is actually showing the change in element stress between runs. The actual data is: Study % element/node difference 1 3 2 1 3 1 4 1 5 0

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...
