Is the high stress at one node or over an area? Also is the node in a sharp corner?
Thanks for your reply. Yes, it is around the edge of one of the holes where the bolt connections have been defined. The edge is located between two plates on nut side.
My questions are:
First, why I can't see this high stress concentration in principal stress' values as well.
Second, how should I interpret the results? Since this Von Mises stress is far above yield stress.
Third, what measures do I have to take to reduce the effect of this high stress? The part a simple support bracket made of steel plate.
Many thanks in advance,
What are the minimum principle values? Near the bolts the bracket might be in compression hence a negative value. I hope this helps.
