The object I analyze is basically a steel plate with
some stiffeners. I model it with shell type elements.
I find out that the stress at sharp corners of
critical joint reports incredibly high. And the stress
value tends to increase endlessly against mesh size.
The smaller the mesh I model in this area, the higher
the stress I get. In that case, I can never achieve a
stress level below yield point of steel and I afraid
the final structure would be over designed indeed.
Is this something to do with gStress Singularityh.
If so, can anyone kindly explain what is gStress
Singularityh and how can we interpret our results in
light of this problem.
Appreciate you guys help.
