| Abstract: | 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. |

| Keywords: | free conical shell strain-rate sensitivity dynamic elastic-plastic deformation |
