Effect of Follower Force on Vibration Frequency of Magneto-Strictive-Faced Sandwich Plate with CNTR Composite Core

This study deals with the vibration response of sandwich plate with nano-composite core and smart magneto-strictive face sheets. Composite core is reinforced by carbon nanotubes (CNTs) and its effective elastic properties are obtained by the rule of Mixture. Terfenol-D films are used as the face sheets of sandwich due to magneto-mechanical coupling in magneto-strictive material (MsM). In order ...

Numerical Simulation of a Flexible Plate System for Vibration Control

This research presents an investigation into the numerical simulation of a flexible thin plate using Finite Difference (FD) and Finite Element (FE). Based on the FD method, an appropriate model of a thin plate was derived and its corresponding natural frequencies were estimated. Then, FE modeling of the plate system was implemented using the ANSYS software and the corresponding modes of vibrati...

Experimental study on vibration characteristics of sandwich beams with aluminum skins and magnetorheological elastomer cores

Magnetorheological elastomer (MRE) material consisting of a natural or synthetic rubber filled with micron sized iron particles is a smart material whose properties can be controlled by a magnetic field. In this paper, experimental study on the dynamic characteristics of an MRE core embedded sandwich beam is carried out. Frequency responses from experimental results on MRE cored sandwich beams ...

A Numerical and Analytical Solution for the Free Vibration of Laminated Composites Using Different Plate Theories

An analytical and numerical solution for the free vibration of laminated polymeric composite plates with different layups is studied in this paper. The governing equations of the laminated composite plates are derived from the classical laminated plate theory (CLPT) and the first-order shear deformation plate theory (FSDT). General layups are evaluated by the assumption of cross-ply and angle-p...
