This paper presents the finite element analysis of the dynamic crack propagation in brittle material namely, Gray cast iron. The analysis is done by using remeshing technique. Dynamic fracture deals with fracture under conditions where inertia forces must be included in the problem formulation. This occurs either under dynamic loading or in the case of static loading as a rapidly propagating crack runs through a structure. In present paper fracture analysis of the RDCB (rectangular double cantilever beam) specimen and the unknown crack tip position and unknown crack velocity is computed during the analysis by the dynamic fracture criterion. According to the new crack tip position, a remeshing technique has been used to simulate the dynamic crack propagation and compared with the experimental result.
