| 英文摘要 | Based on the edge-based smoothed FEM (ES-FEM) and the partition of unity, the first major items of Williams' series for the displacement field near the crack tip are incorporated in the test and trial function space, resulting in the enriched ES-FEM formulation, eEF-FEM. The eES-FEM does not differentiate any shape functions, avoiding the treatment of the 1/r singularity in computing the stiffness matrix. The complexity of computation is accordingly reduced. Meanwhile, it is pointed out that the variational foundation of the eES-FEM is the generalized Galerkin method. Typical numerical examples are analyzed, suggesting that the results of the eES-FEM are much better than either FEM or ES-FEM. |
