Abstract: A simple model for the cracked cylindrical shell is employed to explain how dynamic values of the elastic stress-intensity factor may exceed twice their corresponding static values. Static stress-intensity factor calibrations are available in handbooks and compendia and there exist various numerical and analytical techniques to compute the mode-one stress-intensity factor K//I for unique configurations. Although some researchers have considered wave propagation effects on crack tip stresses in beams and tensile strips, information about the long-time behavior of the quantity K//I in finite geometries under dynamic loading conditions is less commonly encountered in the literature. Recently Petroski and Glazik considered the time-dependent behavior of K//I for a variety of cylindrical shells with cracks, and it has been possible to generalize about this response when vibrational effects dominate the problem.
