Stress around circular hole
Stress around circular hole
(OP)
Hello Guys,
I have a bracket with a hole and when I perform FEM analysis i get stress concentration around the hole. My question is can I use plastic stress field around the hole? And if i'm using plastic stress , to which value I will compare ? Do we have a code or standard reference stating that we can take the plastic capacity around the hole?

the reality is that at a (any) hole is almost any structure there is a highly localised plasticity that has little bearing on the load capacity of the part. Once the plastic stress becomes global in the model (and not isolated local break-outs) then "the game's up".
another day in paradise, or is paradise one day closer ?

FE analysis - linear or nonlinear?
Application - steel girder for building or aircraft spar web?
