A common test specimen for studying the dynamic characteristics of a crack is that of the so-called double cantilever beam. A starter crack is usually introduced at one end by a wedge action splitting the beam at the mid-section and producing an initial crack of certain length. Depending on the loading condition the crack first picks up speed and then slows down as it increases in length. This work is concerned with the effect of material nonlinearity on the motion of a running crack. An extensive amount of theoretical results are presented, with details of velocity and acceleration related to time and crack length parameters. The results are useful to the experimentalists for collecting data on the dynamic fracture of engineering materials.
