Tire has become one of the most complex finite element analysis project. Because tire has special hyperelastic characteristics. Unlike homogeneous metal property. Tire also can be assumed as complex composites. Since the inside consist of many materials, such as different kind of rubber, steel belt, polyester, and so on.
So its kind of tricky treatments of analyzing tire and its behavior afterwards. I had performed many tire simulations in order to predict tire performance and behavior. There are inflation analysis, footprint analysis, rolling analysis, cornering analysis, load analysis even hydroplaning analysis. In finite element, you will have unlimited boundaries to model whole processes to achieve goals.
Here are some procedures to model a tire.
