Modeling the Bolt and Preload

Evaluation of the structural integrity of assemblies often involves proper modeling and analysis of bolted connections, including the consideration of bolt preload effects. The preload on bolts makes it possible for forces to be transferred between clamped parts effectively, whereas loose bolts may cause failure. Preloaded bolts are also often used in applications with liquids to prevent leakage, so bolt preload is a necessary component of such simulations.

A course completion badge allows you to showcase your success. We partner with Credly’s Acclaim platform, and digital badges can be used in email signatures, digital resumes and social media sites. The digital image contains verified metadata that describes your participation in our course and the topics and skills that were covered. This badge is for successfully completing the Modeling the Bolt and Preload course.
