How to apply preloads to a bolt model in Simcenter with Nastran solution 402

https://www.mayahtt.com/products/simc... Questions about preloads are common. If you've ever wondered how to model a bolted connection or how to model the bolt torque in an analysis, this video has the answers. You'll see how to apply bolt preloads to a model in Simcenter with Nastran solution 402 as we demonstrate the nonlinear material capabilities of SOL 402. You'll see how to easily: • Idealize the bolt for meshing (Split body) • Mesh the bolt • Create a Preload subcase in SOL 402 • Create a Preload load Starting in the idealized part, we cut the bolt in half to create a plan to apply preload. Next, in the FEM, we added mesh mating conditions to each bolt to ensure a continuous mesh. In the SIM, we used preload subcases to establish preload before the internal pressure was applied. This is how you define a preload on 3D elements using the cut-plane method in Simcenter NX. Check out our related video on how to simulate a flat gasket in Simcenter with Nastran solution 402.
