The dynamic motion of an axially oriented through crack in a pressurized cylinder was studied numerically. Both small and large deflection theories were used, with the results suggesting that large deflections may be important for elastic, but not for plastic stress fields. Computations were also made with pressures predicted by consideration of fluid outflow through the crack and indicate that the crack shape near the tip is independent of the pressure profile.
