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:Structural Mechanics Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
