Abstract:
An examination is made of the effects of structural damping on the axisymmetric forced vibrations of a cylindrical sandwich shell. The analysis is formulated by two methods, one exact but leading to lengthy calculations, the other a simple approximate formula requiring only a knowledge of the natural modes. In numerical examples, two steel-faced sandwich cylinders are compared. One has a polymeric, the other an elastomeric core. The results indicate that under a time-harmonic radial pressure they are both effective for suppressing resonant vibration, the polymeric core being generally more effective than the elastomeric core.
