Predicting and Validating Welds with FEA in Nastran In-CAD

Would you like to improve your ability to successfully account for welds in your finite element analysis (FEA) simulation?
Many engineers are modeling welds inside of weldments using FEA with varying degrees of confidence on weld stresses. We take a look at challenges in predicting stress in welds, and common techniques for modeling welds in the FEA environment. Several guidelines are given for outcomes we should expect when modeling welds. After viewing this webinar, the tips and tricks should improve the user’s ability to successfully account for welds in their FEA simulation.

everyone believes the numbers from the fea analysis expect the one who did it :D

If the body is circular how would be the procedure?, thanks!.

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? Thanks in advance.

Welding requires extensive benchmarking based on your application/industry. It's as good as aiming in the dark.

The stress values typically increase at sharp corners when refining your mesh, up to a certain point. Is your problem at a sharp corner? In real life there is alwast a small smooth transition at the weld toe. If the stress goes to infinity the more you refine your mesh, then you have a stress singularity
