As I understand it, the notch shown in the image will be filled with weld, right?
If that's the case, simply fill with base material. Remember that stresses in or at the toe/heel of a weld are never accurate so don't get hung up on the local results. This "fill" material should ensure that the load transfer is correct.
ok, i understand, but... filling with the base material, shouldn't i get the same result as using some link connectors? (as fill with base material i assume that is to drawing the part without the notch right? )
Pedro, I think what Adam means is to do the part without the notch. As he said, the stresses there are never accurate (heat affected zone and possible phase transformation that COSMOS can't simulate). On the other hand, if the weld is done right the part should never fail at the weld (this is what AWS tests for).
Moreover, using link connector between 2 surfaces STIFFENS THEM a great deal.
If these surfaces are small (e.g. two pin holes) this can be acceptable.
On the contrary, if you connect the two sides of the flanges, you are going to make the corner unbreakable.
Fill the gap with a solid feature.
thanks all, i fill the gap with a solid feature and it solves all my problems...
