Helpful Hints and Tips: Application of Bolt-Preload via Multi-Body Contact
Abstract: Two options are available for representing pre-loading of 3D bolted joints:
- Shortening of the bolt shank length to interfere with the plate surface and induce tension on the bolt
- Applying a negative ΔT to the bolt shank elements via a thermal load

“Of the three FEA products we use, StressCheck® gives me the most confidence when it comes to performing post-processing quality checks on multi-body contact analysis results. StressCheck® has the capability to extract any data of interest and convergence information for that data at any location in the model domain; the other two FEA products do not. And when it comes to interference fit multi-body contact solutions, I haven’t found any software to outperform StressCheck®.”
