✦ Synopsis

Stress analysis is carried out for the case where a thin cylindrical shell reinforced with a ring at its mid-point is subjected to impulsive inner pressures. The relationships between the maximum dynamic stresses, the dimensions of the cylinder and the ring are obtained. The fundamental equation of motion of the cylinder is solved by the Laplace transformation method. From the results of theoretical analysis, it becomes evident that the range influenced by the reinforcing ring (on either side) is about 4x/'~ in length (where R and h are mean radius and thickness of the cylinder) when pressures are applied statically, but this range becomes very wide when pressures are applied impulsively.
