Abstract

Starting from the dynamic response of a sandwich beam with damping, (which is in free vibration), it is established a method used to determine the damping factor. We experimentally calculated the stiffness and damping factor per unit mass for beams with middle layer made of polypropylene honeycomb respectively; the external layers were made of epoxy resin reinforced with steel fabric. Keywords: sandwich beam, stiffness, damping factor, steel fabric, polypropylene honeycomb, free vibrations
