Hi Rothers,
Thanks for your reply.
"Nominal stress" I said is the type of stress Bs 7608 Standard used to get stress range (nominal stress = F/A Link).
However, using the FEM method, I get only stress tensor, principal tensor but nominal stress.
So how can I pass this obstacle?
Hi everyone,
I am conducting a simulation to calculate stress in order to estimate fatigue of a 3D structure.
In Bs code standard I used, they use nominal stress or hot spot principle stress to calculate stress range and then use it to s-n curve, however, as far as I know, FEM cannot calculate...
