Simplifying assumptions in modeling, such as replacing bolted connections with bonded contacts, are made to reduce computational costs while aiming to maintain engineering accuracy for the application. It is true that in some cases, these simplifications can lead to an underestimation of stress levels.

The model used for the bolt: 

  • Solid models offer the best precision and give the most information
  • Beam models can be used if some inaccuracy is acceptable.

Thanks,
