Determine maximum stress in steel plate

Anonymous — Thu, 13 Feb 2020 15:27:31 GMT

We are trying to determine the maximum stress in the steel plates forming a fabricated box section that adapts shape at it's connection and prove the steel plate can carry the applied loading.

The attachment shows what we understand to be the maximum von Mises stress in the plates under ULS loading (maps/complex/Stresses-s)

How do we compare this stress against the steel grade, in this case S355 to prove the plate does not yield?

Thank you,

Hi @Anonymous

Von Mises stress criterion is commonly used for estimating if metal structure failed due to yielding.

Von Mises stress can be comared directly with yield stress limit.

There are many articles about that in net

As an example please refer to Von Mises criterion (conclusion section)
