Abstract: | An analytical model of a rigid, linear-hardening plastic tube subjected to impulsive torsion at its free end is suggested. It is shown that an impulsive torsional moment at the free end of the tube gives rise to a torsional disturbance of strong discontinuity that propagate at a constant speed and the plastic deformation is concentrated at the front of the disturbances. Two examples are given to illustrate the characterization of the structure under the intense dynamic pure torsional loading condition. |
