This paper describes the 3D complicated crack propagation analysis using the Free Mesh Method (FMM). The computational fracture mechanics involves frequent re-meshing as the crack propagates. In order to show the effectiveness of the FMM in crack propagation analysis, we study the 3D Complicated crack propagation problems with the FMM. Comparing with 2D analysis result, the 3D effect on crack propagation is studied.
