Bolt pretension, as the name indicates, involves applying initial tension to the bolt before any external loads are introduced..
This ensures the joint remains tight and stable, even when subjected to various forces and vibrations.
The main goal of bolt pre-tensioning is to create a clamping force that holds the joint together, preventing it from loosening under operational loads.
It is used in critical applications such as structural connections, machinery, and automotive assemblies where joint integrity is crucial.
In this analysis, we subjected a bracket to pretnesion through a bolt.
