This is a difficult one: how can one dimension welds in structures that are subjet to dynamic loads ? Dynamuc analysis doesn't offer edge weld check plot, and I'm not sure if you can compute free body forces.
Well, you can try taking the load history used in the Dynamic analysis and using it as a load load history in the rainflow method, scale it to get the right magnitude of stress. then compute the life in terms of the length of the dynamic analysis previously run.
Thanks Bill, interesting method you are describing. I've never gone in-depth for what concerne fatigue Analysis on welds with solidworks simulation. Can you address me to a web cast/document/forum thread on the subject ?
