We have already proposed a simple procedure for obtaining stress intensity factors by the finite element method. The applicability of the simple procedure for the elasto-dynamic problem is investigated in detail. Particularly, the dynamic stress intensity factors for the opening mode deformation crack are investigated in this paper. The application of the simple procedure is demonstrated with several problems. As sufficient results are confirmed by the investigations, the dynamic stress intensity factors for a centrally cracked rectangular strip subjected t suddenly applied and sustained tension are calculated by using the simple procedure for various ratios of the crack length to the plate width systematically, and the relation of the dynamic stress intensity factor and the static one is investigated.
