Abstract : The report deals with the dynamic response of a thin finite, elastic circular cylindrical shell representing a naval vessel to time-dependent loadings symmetric with respect to the axis of the cylinder. The shell contains an axial through crack of length 2c. The dynamic counterpart of Donnell's shallow shell equations are used in this investigation. Extensive numerical results are presented for stress intensity factors in aluminum and steel vessels and results are discussed. (Author)
