Authors: | Li Xianglian |
| |
Abstract: | Penalty element method and derivation of penalty element stiffness matix are described. The method can be used not only to solve the displacement conformance of cyclosymmetrical substructures, but also to determine the substructure constaints. The relative calculations are taken as examples to show the validity and the rationality. |

Keywords: | cyclosymmetrical substructure penalty element constraint |
