Structural and Fatigue Analysis of a Car Wheel Rim

Firstly, the parametric solver is used to simulate a varying load along the boundary of the rim. The model solves for both the anti-symmetric and symmetric load cases. The two solutions are then combined in COMSOL Script in order to retrieve the full solution for the stresses and deformation of the wheel rim.

In a second, extended example, a fatigue analysis of this car wheel rim is performed by utilizing the fatigue tools available in the Structural Mechanics Module.
