• This paper is concerned with a theoretical analysis of the dynamic plastic deformation of thin cylindrical shells under internal impulsive pressure. The shells are assumed to be made of a perfectly-plastic rigid material that obeys the flow rule of von Mises. The dynamic pressure is suposed to be such that at some given time a uniform radial velocity is instantaneously imparted to the entire shell wall lying between the reinforcing rings. It is possible to set up certain equations of motion on the basis of a few assumptions concerning stress-strain relation. Under certain conditions the expressions for principal stresses, radial velocity and displacement of the shell wall, deformation time and bending wave velocity are obtained in simple closed forms. The profiles of deformed shell are specified in three different types depending upon the distance between rings.
