✦ Synopsis

BEAMS

Analysis for the dynamic response of two layer and three layer viscoelastically damped beams subjected to half sine shock excitation has been carried out. Effects of rotary and longitudinal inertias have been included in the analysis in addition to the effects of transverse inertia. The properties of the viscoelastic material have been represented by those of a four element viscoelastic model. The constants of the model have been determined for a viscoelastic material for which properties are known for maintained harmonic excitation. Experimental verification of the analytical results for strain response due to shock excitation is reported.
