Vibration and damping analysis of cantilever sandwich plates with viscoelastic core using zig‐zag theory

Abstract

AbstractIn the present work, an FE formulation using the zig‐zag hypothesis is developed for cantilever sandwich plates with viscoelastic care layer. Both viscoelastic and elastic layers of sandwich structures are considered based on the first‐order shear deformation theory to achieve higher accuracy. The FE simulation is validated by a frequency and loss factor analysis of sandwich plate. Furthermore, the damping characteristics and transient response of the cantilever sandwich plates are systematically studied.
