| 摘 要： | This paper studies the dynamic behavior of large deformation of sphericalshells impacted by a flat-nosed missile.By using isometric transformations,thedeformation modes are given.On the basis of Perzyna-Symonds viscoplasticconstitutive equations,the motion equations of the shells are obtained by rigid-viscoplastic variational principle.A comparison made between the numerical resultsand experimental ones indicates that the two groups of results are in conformity witheach other.
