Tire Inflation
Application ID: 118091
This model showcases how to use fibers in thin layers to model thin anisotropic composites embedded in a solid without explicitly drawing either the layer of material or the reinforcing fibers. Here, it is used to model steel cords in tire belts that are used to provide structural support to the tire below the tread. Moreover, a curvilinear coordinate system is used to define the anisotropic material properties of the carcass ply.
The model also makes use of the “twist” degree of freedom in 2D axisymmetry to capture the azimuthal displacement induced by the orientation of the cords during inflation of the tire.
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:
- COMSOL Multiphysics® and
- CAD Import Module and
- Nonlinear Structural Materials Module and
- Structural Mechanics Module
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 Tabella delle Funzionalità 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.
