Impact pressure loading of rigid-plastic cylindrical shells

Abstract The collapse load of a rigid-plastic body is defined as the smallest load at which deformations become possible. If a load greater than the collapse load is applied, the material of the body will undergo accelerated plastic flow. The present report considers a rigid-plastic cylindrical shell, loaded for a short time with a pressure greater than the collapse load. It is found that the shell is still specified by a single parameter depending on its dimensions, and that four different types of solution exist depending upon whether the load is “medium” of “high”, and the shell is “short” or “long”. Expressions for the stresses, velocities, and displacements are found in each case, and typical results are presented graphically.
