Using Ordinary Fourth Order Beam Theory in Combination with Frequency Dependent Parameters to Predict the Flexural Dynamics of a Sandwich Beam

Abstract

The purpose of this work has been to evaluate the possibility of using modified lower order methods — such as the Bernoulli-Euler or Timoshenko beam theories with frequency dependent parameters — to calculate the response of sandwich beams subject to different end conditions. The models have been verified by measurements on a freely suspended asymmetric sandwich beam with aluminium laminates and a plastic foam core, indicating good agreement.
