It is considered that the elucidation of the dynamic fracture mechanism under a complex load is of very high importance. In this study, fracture behavior by adding an impact load to a rectangular plate with a parallel double notch was discussed using the moving finite element method based on the Delaunay-automatic-triangulation. Since the notch interval is narrow, reflection, refraction, diffraction and interference of the stress wave were generated; this fracture phenomenon becomes the complex mixed mode condition. The various fracture mechanics parameters of this fracture phenomenon were calculated by the use of the numerical analysis. Then, the dynamic fracture path of this experiment was estimated by the propagation-direction criterion which in turn confirmed to agree very well with the experimental results. As a result, the validity of fracture simulation by this technique was shown.
