✦ Synopsis

The Flu¨gge type basic equations for an infinitely long thin cylindrical shell, including the effect of initial tensions due to non-uniform internal pressure, are employed, and by using the complex WKB method the solution of the basic equations is constructed in the form of superposition of the packets of short bending, longitudinal and torsional waves. The dependence of frequencies, group velocities, amplitudes and other dynamic characteristics upon variable pressure is examined.
