| Abstract: | In this paper, the dynamic response of a rigid-plastic circular ring, which is supported at its bottom by a wedge and subjected to a symmetrical impact on its top, is investigated on the basis of the large deformation formulation. The whole response process of some numerical examples is given. These computing results indicate that the dynamic mode of large deformation is quite different from the static collapse mechanism and the dynamic mode of small deformation. |
