Corner stress vs Center stress, which one shall be used ?
Corner stress vs Center stress, which one shall be used ?
(OP)
I am doing some FE analysis using plate element in the STAAD model.
For the analysis result I always use max Von Mise stress at center of plate (center stress) to compare with steel's yield strength.
Some other engineers spot that some plate's corner stress is 30% more than the center stress and exceeds material's yield strength.
Shall I ignore the larger corner stress value and only use center stress for comparison?
What's the relationship between corner and center stress in STAAD ?

Any other FEA program I've ever used allows you to get the average stress at a node, usually just by putting your cursor over the node or clicking on it.
And wait until you have to explain this corner stress to the client. "Oh Mr. Client, that stress is fictitious. You have to add the stress in the corner of each of the other three elements that share this node to the one we're looking at and divide by four."
Back to your question, no don't ignore it. Try to understand why it's happening.
