All structural analysts know that finite element analysis (FEA) results can only be as accurate as the underlying assumptions within the model itself. However, modeling discrete fasteners with solid elements, contact, and bolt preload can add significant complexity to otherwise linear models and quickly becomes computationally prohibitive.

This webinar will consider the best practices associated with simplified fastener representations, with a focus on approximations using rigid and beam or spring elements, which still provide realistic stiffness representations and can even allow for robust strength assessment of each bolted joint. After introducing the best practices, the webinar will showcase how to implement these approaches with a live Femap demonstration.
