Tire Engineering by Finite Element Modeling 840065

Finite Element Modeling (FEM) is a powerful technique for stress analysis of a structure that is too complex for classical mechanics. The pneumatic tire is indeed complex with its large displacements/large strains, follower type loading, and nonisotropic material properties.The paper helps to explain finite element modeling in plain language terms that most engineers will feel comfortable with. The paper demonstrates the state of the art in FEM tire engineering and pre/post-processing computer aided engineering (CAE) techniques.Examples of results are shown, along with experimental verification. The length of a FEM computer solution is addressed with comparisons made between coarse and fine grids, and 2D versus 3D.Future trends in tire engineering are reviewed.
