Dynamic Analysis of Delaminated Sandwich Composites
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 1
Abstract
ABSTRACT: The analytical formulation for free vibration of sandwich beams consisting of two different layers and is split along the interface with single and multiple delaminations is presented here. The influence of the delamination size and location on the natural frequency is investigated experimentally for beams with single delamination and the results agree well with present analytical formulation. Modal analysis has also been conducted using finite element package ANSYS and has been compared with the experimental results. It is observed that the delamination reduces the natural frequency and change the mode shape. To identify the exact location and extent of delamination, strain plots are used.
