Summary | This study deals with the modeling by finite elements of an elastomeric composite structure. The main difficulties lie in the heterogeneity of the piece and in the geometrical non-linearity due to the centrifugal forces. We use the combination of two different methods of level sub-structuring. The first one is a multi-level sub-structuring method and the second is a more classical sub-structuring. After computation, the complete solution in displacement, the complete stress field and the global dumping of the structure (by an energetic method) are obtained. |
Keywords | finite elements method, sub-structure method, dumping, large number of degrees of freedom, heterogeneity, geometric non linearity, elastomer, composite material. |
