Unique Method for Simulation of Bolt Pre-Load
This paper describes the modelling approach for simulating bolt pre-loads when there is interference in the bolt-nut CAD or in the FE model. In general, the Bolt and Nut will have interference in the CAD at the thread region during the CAD modelling. When it comes to simulation, either interference regions are de-featured or ignored. There will always be a question on the validity of results when assumptions like beams with rigid elements or bonded contacts are used for simulating the boltsdoi:10.6084/m9.figshare.14178542.v1 fatcat:4db3wmawfrbldeg6ddwrx6hidy
