Asymmetric transient response of a hollow cylinder enclosing a compressible fluid

The asymmetric transient response of a hollow cylinder confining a compressible fluid is analyzed. The cylinder is excited by radial displacement prescribed over a rectangular footprint on the cylinder’s outer surface. The special case of plane-strain is also analyzed. A comparison of dilatational stress in the solid cylinder and fluid pressure in the fluid-filled cylinder reveals how a projectile may decelerate faster in the latter.
