摘　　要：本项工作是用ABAQUS程序对受瞬间压力作用的自由圆锥壳做数值模拟解,求得了在几毫秒时间进程中较为详细的物理图象。This work with ABAQUS code is a computational solution of the free conical shell subjected to a kind of transient pressure in some area. The material of this shell includes strain-rate sensitivity. This paper demonstrates its main patterns in several milliseconds of the response. The patterns are :the stronger stresses, the plastic yielding is mostly taken in the loading area, the wave phenomenon of the circumferential stresses, the wave phenomenon of the axial stresses, the deflections of the whole shell are ' breathing' and corrugated.
