The Effect of Structural Damping on the Forced Vibrations of Cylindrical Sandwich Shells

Résumé du livre

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.
