Transient Rolling Contact
Application ID: 39561
This conceptual example shows how to handle a transient contact problem with stick-slip friction transition. A soft hollow pipe subjected to a gravity load is released at the top of a halfpipe. The pipe motion varies between sliding and rolling, depending on its position in the halfpipe and its velocity. The cross section of the pipe is also ovalized due to the contact and inertial forces. An energy balance validates the accuracy of the solution.

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