Hot spot stress design methodology

Question asked by Alessandro Tornincasa on Sep 27, 2012


I need to make an analysis to check welds fatigue life on the parts you see here:

I've read that, when welds fatigue analysis is involved, you need to use an hot spot stress design method. I've found documentation about it, like attached PDF article.


I've seen also COSMOS Companion videos, which show how to check and size weld on the basis of forces and moments acting on the welds. Hot spot method is based rather on stresses.,


Are there anywhere on the internet any examples of the ot spot stress design method applied with solidwoks simulation or maybe other codes ? Or is there any documentation showing practical application examples ?

It would be very interesting on a part as simple as this.
