| Abstract: |
| In this paper, a new hybrid finite element model was developed to analyze singular stress fields around an inclusion corner. A super inclusion corner element is needed to build in the analysis. The stiffness matrix of the element is established with the eigen solutions of rectangular inclusion problems. The method is used to compute singular stress fields around a rectangular inclusion embedded into an infinite homogeneous plate. The numerical results were compared with the available numerical solutions. The comparisons show that present method is applicable and effective, and yields numerical results with high accuracies and is more suitable for complicated engineering inclusion problems. Finally, mechanical or electro-mechanical behavior near a rectangular inclusion corner in anisotropic materials or piezoelectric materials is discussed. |
