This bolt type uses a beam element for the shank and shell elements for the head and nut. An important note is that the PID of the head and nut need to be added to *CONTACT_AUTOMATIC_SINGLE_SURFACE. Null beams can also be added to the model to help with the contact. The benefits of this method are that it can capture the onset of slipping. The drawbacks are that this method can be tedious if the hole bearing behavior needs to be investigated. Also, this technique is not good for calculating bolt shear failure.
