Vince Adams and Dean Rose investigate the world of weld prediction and validation in this installment of the Nastran In-CAD webinar series. The webinar focuses on weld terminology, 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.
