Forced vibration and special effects of revolution shells in turning point range

The forced vibration in the turning point frequency range of a truncated revolution shell subject to a membrane drive or a bending drive at its small end or large end is studied by applying the uniformly valid solutions obtained in a previous paper. The vibration shows a strong coupling between the membrane and bending solutions: either the membrane drive or the bending drive causes motions of both the membrane type and bending type.Three interesting effects characteristic of the forced vibration emerge from the coupling nature:the non-bending effect,the inner-quiescent effect and the inner-membrane-motion-and-outer-bending-motion effect.These effects may have potential applications in engineering.
