(ABAQUS CAE) piezoelectric analysis


I'm doing piezoelectric analysis using abaqus CAE v6.12.

Specifically, what I'm doing now is to make the bimorph piezoelectric harvester model using Abaqus CAE

and to validate my model.

My FE model is made based on the model developed by A Erturk and D J Inman in their paper,

'An experimentally validated bimorph cantilever model for piezoelectric energy harvesting from base excitations'

They presented the analytical solution for voltage output and experimental validation is also presented in this paper.

Piezoelectricity above the Curie temperature? Combining flexoelectricity and functional grading to enable high-temperature elect

Most technologically relevant ferroelectrics typically lose piezoelectricity above the Curie temperature. This limits their use to relatively low temperatures. In this Letter, exploiting a combination of flexoelectricity and simple functional grading, we propose a strategy for high-temperature electromechanical coupling in a standard thin film configuration.

Phononic crystal with adaptive connectivity: A new approach to 'smart' materials

In recent times, mechanical metamaterials and a phononic crystals have attracted the attention of some groups, as they allow to exploit on a larger scale phenomena known from solid state physics, such as the creation of band gaps at certain frequencies. The peculiarity of metamaterials is that their effective properties emerge from the periodic geometric organization of their unit cells rather than from the constituting bulk materials. Furthermore, metamaterials can be built in any size, ranging from the nanometer to the meter scale, and out of any material to suit different needs.

Laminated composite smart stiffined plate

I am working on topic ' Finite Element Analysis of laminated composite smart stiffened plate'. I am not getting proper proper mathematical formulation for using in coding for MATLAB program.


Hi colleague

 does anybody know, what is this strange error :   Error in connection to analysis

i am trying to model fracture mechanics on piezoelecteric material, when i select the piezoelectric as a familiy in mesh part, then when runing the model, i recieve this error. if anybody knows how to fix it please help me.thanks

The piezoelectronic transistor: A nanoactuator-based post-CMOS digital switch with high speed and low power

A review article of our research at IBM TJ Wason Research Center in piezoelectronic transistor, an exploratory device beyond silicon, is published in MRS Bulletin, Volume 37, Issue 11, November 2012, pp 1071-1076. Your future computer may depend even more on the mechanics.

Transverse moduli for composite

I'm currently working on modeling 3 phases composites material. However, I'm having hard time on finding the transverse modulus as it's different from analytical results. I've been using Mori-Tanaka approach to determine the stiffness moduli. Does anyone know how to obtain a correct values for the transverse moduli?

About piezoelectric resonance.

For 31 mode piezoelectric plate. I have measured it's electric impedance spectrum (curve of Log IZI~ Frequency). I found that, when I used this plate for a piezoelectric sensor to receive mechanic signals. the maximum output  occured at antiresonance frequency;   For example, for piezoelectric hydrophone or receiving-type piezoelectric transducers, It works at antiresonance frequency (at the maximum electric impedance).
