摘 要: 本文对底部支承在劈尖上顶部受刚性质块对称冲击圆环的塑性动力响应作了大变形分析,给出了具体算例的响应全程解,得到了动态变形模态不同于静态塑性破坏机构以及大变形响应与小变形响应不同等结论。 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.
