✦ Synopsis

In accordance with two different methods, we shall first prove that the dynamic stress intensity factor of mode I of an infinite sheet with a central crack propagating at constant velocity is independent of material constants and the uniform velocity. Then. we may give the general solutions to the more complicated problems of an infinite plate weakened by aiinfinite series of douhly periodic cracks moving at constant velocity under concentrated forces P and 0 in this paper. Of course, the dynamic stress intensity factors of them are also independent of material constants and the uniform velocity. It is clear that the conclusiont should be very valuable for designers and experimenters.
