Abstract
The dynamic response of a circular ring, which is supported at its bottom by a wedge and impinged by a rigid mass on its top, is analyzed on the basis of rigid-perfectly plastic idealization and the small deformation formulation. The effects of the "mass ratio" and "energy ratio" on the deflection at the impinged point are shown by numerical results. The results also indicate that the dynamic plastic deformation is mostly localized in the region near the impinged point, and this makes the dynamic mode quite different from the static collapse mechanism
