An anisotropic model was considered as a rectangular plate made of fiber reinforced plastic with an edge crack parallel to the fiber direction. Its dynamic response was investigated by comparison with the results for an isotropic plate from the point of view of the time response of the dynamic stress intensity factor determined by the finite element method. First, by the qualitative elucidation for the dynamic response of this model subjected to a step function load, the influence of an anisotropic composition on it was made clear. Continually, analyses provided the duration time of the incident stress wave were performed, and according to those results the fracture of the anisotropic model was predicted and it was compared with the experimental results.
