Prestress of Main Bearing Cap Bolts

Application ID: 55961

This example shows how to model prestressed bolts.

The bolt geometry is taken from the Part Libraries.

For comparison, one of the bolts is modeled using a thread contact formulation, whereas the other bolt is connected to the bolt hole by a pure continuity condition. The reduced stiffness in the threaded part of the bolt is taken into account by a reduction of the stiffness of the material.

This model example illustrates applications of this type that would nominally be built using the following products:
