Predicting and Validating Welds with FEA in Autodesk Nastran In-CAD

[@richardwhitfield]

Really like these videos, unfortunately my time zone doesn't allow a live listen so it's great that they are on KZbin. Many thanks guys.

This webinar is really useful. Thank you very much. Is there one about weld sizing under fatigue loads?

[@kristianSilva95]

Amazing webinar! Really helpful (regardless of the software youre using)

[@jeremieblais8274]

I think it's important to mention that the safety factor of 1.7 to find the allowable stress in a weld IS NOT the same safety factor of the equipement you are designing for a given purpose. In this example you have a nominal force of 10 000 lbf, and you want to design with a safety factor of 2, you should put 20 000 lbf in the Weld Calculator! If you fail to do that, all the welds will be sized with a nominal safety factor of 1, which can be dangerous if you are designing lifting devices or below-the-hook devices.

Can you clarify further... Does the 1.7 only account for the weld being assessed in shear? If so I think it is misleading to call it a safety factor.

[@SuperApeDude]

Can someone please help me out here. When I do this analysis, if I refine the mesh, the output lb/in values increase. Aren't these values supposed to be mesh "insensitive"? Obviously this is an issue as the calculation then tells you you need a bigger weld if you have a more refined mesh. What am I missing here?

In practice we always take the max values not the average.

Considering the vast majority (95%) of engineers work in metric why is this in inches?
