Dynamic response of plastic spherical shells under impact

摘要

This paper presents a theoretical analysis of the large deformation problem of a plastic spherical shell impacted by a missile. Firstly, a deformation mode of the spherical shell is given by introducing isometric transformation. Secondly, the large deformation problem of a rigid-plastic spherical shell is solved. A comparison between the theoretical results and the experimental ones indicates that the two groups of results are in conformity with each other.
