| Abstract: | The scattering of elastic waves, both the torsional and tensional waves, due to a circumferential through-crack in an infinite cylindrical shell is investigated by the classical thin shell theory. The reflection coefficients and stress intensity factors are calculated. The numerical results are examimed by an application of the balance of rates of energy. |

| Keywords: | elastic wave scattering dynamic stress intensity factors asymptotic analysis |
