PHASE VELOCITY CURVES ON NEW ARBITRARILY HIGHER ORDER PLATE THEORY

On the Buckling the Behavior of a Multiphase Smart Plate based on a Higher-order Theory

Magneto-electro-elastic materials are multiphase smart materials that exhibit coupling among electrical, magnetic and mechanical energy fields. Due to this ability, they have been the topic of numerous research in the past decade. In this paper, buckling behavior of a multiphase magneto-electro-elastic rectangular plate with simply supported boundary conditions is investigated, based on Reddy’s...

Finite element analysis of the piezoelectric vibrations of quartz plate resonators with higher!order plate theory

A _nite element formulation of the piezoelectric vibrations of quartz resonators based on Mindlin plate theory is derived[ The higher!order plate theory is employed for the development of a collection of suc! cessively higher!order plate elements which can be e}ective for a broad frequency range including the fundamental and overtone modes of thickness!shear vibrations[ The presence of electrod...

Repulsion of phase-velocity dispersion curves and the nature of plate vibrations

Measurement of phase velocity dispersion curves and group velocities in a plate using leaky Lamb waves

The guided wave has been widely employed to characterize thin plates and layered media. The dispersion curves of phase and group velocities are essential for the quantitative application of guided waves. The technique using leaky Lamb wave (LLW) is one of the excellent methods to obtain dispersion curves. In the present work, a fully automated system for the measurement of LLW has been develope...

Free Vibration of a Thick Sandwich Plate Using Higher Order Shear Deformation Theory and DQM for Different Boundary Conditions

In this paper, the effect of different boundary conditions on the free vibration analysis response of a sandwich plate is presented using the higher order shear deformation theory. The face sheets are orthotropic laminated composites that follow the first order shear deformation theory (FSDT) based on the Rissners-Mindlin (RM) kinematics field. The motion equations are derived considering the c...
